Woow, quite a piece of work!  Is this based on Marius’ earlier work?
https://lists.gnu.org/archive/html/guix-devel/2018-04/msg00001.html

The policy for Guix is to accept free software packages; this one
clearly fits the bill.

Now, it would be unusable, unless/until Guix System supports systemd (an
option I do not support).  For example, ‘guix install systemd’ wouldn’t
be of any use, right?

All in all, with my co-maintainer hat on, it seems to me that the
maintenance cost would be high (because it’s a large piece of software
that evolves very quickly), for a package that’d be practically
unusable, so I’d lean towards not including it.

WDYT?

Thanks,
Ludo’.

Hi,

Yes, it is based on mbakke's work, I updated the version to latest stable and fixed the new errors :)

I'm quite happy to keep it outside guix if it's not deemed suitable, I was just encouraged to upstream stuff rather than keep things to myself.

My usecase at least doesnt require regular updating, so for things dependent on just "a libsystemd" this would work fine.

Whatever happens happens!

So what’s your use case?

Specifically, what’s the answer to this question:

By knowing the answer and understanding potential use cases, we can make
more informed decisions.

In particular, im using it to relink against a nonfree binary which responds badly to tampering, so im using it only as a library. Others (on irc) expressed interest in using the package, and i can envision other usecases such as container images.

The downside to it being in my repo or being in "another channel" is that anyone wanting to use it then risks nonfree software, and that's already been lamented when i offered to do this in irc.

I'll leave it to your discretion...

[Leo Prikler]

Hello,

As the one, who encouraged the sending of this patch I do have a few
words to say.  First of all, I misunderstood the context -- rather than
systemd as a whole, I thought it would just be some systemd-related
package.  This does not matter that much, since a fully functioning
systemd package would still be nice to have, but it still is important
to distinguish between plain systemd, which doesn't work on Guix for
various reasons and replacement libraries like elogind, which do.

Next, let's address the elephant in the room:

A systemd package, which serves no purpose other than being linked
against nonfree binaries does not sound particularly useful, especially
not when thinking in terms of FSDG compliance.  We don't even know
whether *free* software linked against this systemd would behave as
expected, let alone nonfree software.

This was in part already discussed in IRC, but to reiterate, I think
that the systemd package should be usable in some capacity -- be it,
that we can run systemd as user daemons or be it, that we can
*meaningfully* link free software against it.  Note however, that the
latter most likely implies the first, since there's no meaningful
linkage against systemd without one of its daemons running.

> Others (on irc) expressed interest in using the package, and i can

Interest in a working systemd package has apparently existed longer
than I was aware of, it's just the specifics of the term "working",
that we need to argue about.

> The downside to it being in my repo or being in "another channel" is
> that anyone wanting to use it then risks nonfree software, and that's

I don't think, that's a realistic risk.  For one, people could just
cherry-pick systemd from your tainted channel, but more importantly
you're assuming that the systemd you've packaged works in a context
other than linking it against some evil binary without actually wanting
to use it.  Which is not to say that it doesn't, just that there hasn't
been enough evidence to support that claim yet.

There's nothing wrong with pushing WIP stuff to your own repo or any
other channel that will accept them.  There is however a problem with
leaving them there and not even considering to submit them towards Guix
(assuming that having a package for some given software in Guix proper
is an option, regardless of the current state of the package
definition), because then Guix will be blissfully unaware that a
perhaps even proper package definition for it exists and might thereby
be missing some awesome software.

As far as the patch itself is concerned, there are a few FIXMEs too
many for me to consider it ready -- in particular the double disabling
of tests rubs me the wrong way.  There's also some minor aesthetic
stuff like the "add-shared-lib" phase, which is both not informative
and bound to break with version updates, but I think that should be
manageable.

Going forward, I'd like to ask you (or anyone else willing to package
systemd) to do the following:
1. Can you look into whether systemd or at least parts of it can be run
from the package inside Guix?
2. Can you look into the disabled tests, particularly those, that are
currently just FIXMEs?

Regards,
Leo

Yeah, that’s definitely not a good reason to include it.

Given the maintenance cost, we’d need a more convincing argument than
“should be usable”.  :-)

So it seems to me that we’re done with it as far as inclusion in Guix is
concerned.  Thoughts?

It’s typically a situation where an external channel is more
appropriate, IMO.

I'm definitely leaning towards not including it as-is/perhaps having it
in an external channel as well, but I don't think "high maintenance"
should generally be a deterrent against a functioning package (or
rather the only reason to keep a package from being included).  Guix
already has packages, that I would consider to be of higher
maintenance, e.g. GNOME, and I do think it would help Guix users if
(parts of) systemd became a viable option.  I am simply doubting the
functionality of this package as it currently exists.

That said, I don't think myself to be in a place to make accurate
judgements about entry requirements.  I suggested “should be usable” as
a bare minimum because it seemed easy to convey.  There are also other
things to consider, like coding style, adherence to packaging
guidelines, etc. with maintainability somewhere among them, but I can't
really phrase all of those well into a simple sentence.  I also think
that some reviewer should be able to take an already functioning
package description and perform cosmetic changes to transform it into
one better suited for Guix, though that might be a bit of a
controversial statement.

Leo

I'd also argue that some of the bioinformatics packages are high
maintenance and no one likes having to update them.

One thing that I've noticed with elogind is that it doesn't interact
will with systemd-logind on other machines. Any loginctl command
normally fails because the version we have looks in /var/lib/elogind and
systemd uses /var/lib/systemd.

It would also be useful to figure out how to run user level systemd
services, likely using systemd itself, for those who are interested in
doing so.

I've heard that systemd is modular, in that at compile time it's
possible to choose which modules to build. Perhaps we can build a subset
which are actually useful for us?

I agree with the two of you.  What I’m saying is that if in addition of
having a high maintenance cost, it’s pretty much unusable, then that’s
not good.

Oh you’re saying that someone on a foreign distro might be interested in
running ‘systemctl’ from Guix’ ‘systemd’ package?  That sounds like a
bit far-fetched to me, dunno.

I meant it more like this:

(ins)efraim@g4:~$ loginctl list-sessions

      1  118 sddm   seat0
  12683 1000 efraim seat0 tty2

  15005 1000 efraim       pts/2

4 sessions listed.

SESSION  UID USER   SEAT  TTY
     c1  980 sddm   seat0
     c2 1000 efraim seat0 tty8

2 sessions listed.
(ins)efraim@3900XT ~$ loginctl -H g4 list-sessions
bash: line 1: elogind-stdio-bridge: command not found

It should be possible to interoperate between them

I share Efraim's point — maintenance burden has never been a primary
reason to exclude things from Guix. I think it's important to handle
this patch in a manner that is consistent with the precedent set by
years of Guix code review.

I'm sorry, I haven't read this entire discussion closely. Tony, does
this package seem useful for you?

There is a weird gamergate-esque faction in the free software community
who hate systemd for reasons that are basically inexplicable. It seems
to be one of several proxy battles fought by a far-right [0] political
camp in a struggle over the direction of free software (I'm not sure
*who* they are fighting... most distros just ignore them). We should
recognize their longwinded sophistry for what it is. Systemd works and
it works very well.

Maybe we *should* start rejecting very high-maintenance contributions if
we do not think they will be maintained adequately. But, I do not think
that systemd should be the package that spurs that decision, because of
the special importance that some people have placed on systemd, which
has nothing to do with software, either technically or in terms of
software freedom.

I use systemd extensively with Guix-on-Debian, and it's one component
that I will probably not replace with a Guix package. It's too deeply
integrated within Debian for me to feel confident replacing it, although
perhaps systemctl will work fine when provided by a 3rd party. I really
don't know.

The benefits of Guix on other distros — the strong control over the
dependency graph and ability to modify it and roll it back — do not hold
for systemd, in my opinion. Debian's operating system integration and QA
process is good, at this level of the system.

[0] I know that's a gross generalization, but it just seems that way to
me

Hi leo. As mentioned previously, I do find this useful, I'm using it currently in LD\_PRELOAD for a nonfree package that requires systemd and does not function with elogind patched in instead. Other usecases exist but they're just speculation so far, though the package is otherwise fully functional.

Please describe "fully functional" in more detail.  "I use it to fix
this completely borked proprietary software" is not enough grounds to
assume full feature coverage.  Instead, I'd argue that the disabling of
tests without explanation kinda proves the opposite.

Okay, I was going by the similarity to the nix package, but if you require concrete proof then I just built it without the sandbox and with my kernel supporting cgroups. Exactly 15 test fail, out of nearly 400. Each of them by best approximation due to binaries not in scope and/or systemd not being PID1 (as is repeatedly echoed on the error log).

If those 15 tests pose a concrete issue to you, I would consider fixing them, but only with the guarantee that the result end up in guix. As it stands disposition seems to be to not merge this, so I'll reserve the effort.

15/400 tests failing sounds somewhat reasonable, especially if we can
explain their failure modes (e.g. stuff like not being PID1).  Even if
we add the other tests, that require cgroups on top, that'd be fine,
but we'd have to be able to display all that info in a meaningful
fashion like
  ;; these tests want systemd to be PID1 
  "foo" "bar" "baz"
  ;; these tests require cgroups
  "spam" "ham" "eggs"
  ;; these are missing libquux
  "i" "ran" "out" "of" "funny" "variable" "names"
However, this is somewhat different from the package description at
hand, which lacks those explanations.

The reference point is of course the thing that's compiled within the
sandbox, not anything without.  Having most tests pass when compiling
stuff "normally" with Guix is perhaps a good indicator, that at least
compiling works, but it's really just that.

Finally – and this might be my ignorance of the systemd test suite
speaking, so ignore me if I say something stupid – just because we have
a test coverage of let's say 90% or even 100%, doesn't mean that the
installed binaries will still be able to work.  There is a large
potential for bugs to sneek in, e.g. through an insufficient wrap
phase, so for software like systemd, we should be able to do some
trivial tasks, e.g. `systemctl start hello-world` with a systemd, that
has not claimed PID1.

TL;DR: the plan is to
- Get the sandboxed package to match up as closely as you can get to
the non-sandboxed one w.r.t. testing.
- Document how the remaining disabled tests fail.
- Prove, that components of systemd run when invoked directly from the
store/from within a suitable environment.

It is probably still a somewhat long and bumpy road, but in my personal
opinion one that has an end.

To me, it seems like we are applying a slightly higher standard to this
patch than to other submissions of complex packages whose functionality
is difficult to evaluate.

No no, I was careful to apply the same standards.  :-)  My main
question is whether it’s usable at all:

  https://issues.guix.gnu.org/48924#1

Tony’s use case has to do with satisfying the dependencies of a
binary-only proprietary executable:

  https://issues.guix.gnu.org/48924#2

To me, that use case alone isn’t enough to justify maintaining systemd
in Guix proper.

However, if, as Efraim suggests, a systemd package has some uses, at
least on foreign distros, then that’s fine with me.  It’s a very narrow
use case (running ‘loginctl’ on a foreign distro), but why not.

Thoughts?

Ludo’.

It's true, that's not really a good reason to add the package. There are
probably some existing Guix packages with a similar use case, but nobody
ever said it out loud. It's a lesson in the value of discretion, I
suppose.

To me, it's a simple scenario: We received a contribution to add a
popular free software program.

But it has been complicated by the broader context, about which I
already shared my uncharitable interpretation, and that's a shame. Now
there is a big discussion about it.

I would add the package. We should feel free to remove packages
(especially leaf packages) that aren't building or are far behind the
upstream release schedule if nobody is trying to fix them. We don't have
to assume a burden of maintenance.

The “broader context” didn’t play a role in my comments, really.  :-)

Tony, could you send an updated patch following the suggestions Efraim
and I made?

Thanks,

I'm sorry for suggesting it! I think I am too sensitive about these
matters.

This actually works better for on Guix System than on a foreign distro

(ins)efraim@3900XT ~/workspace/guix$ /gnu/store/khpdv70slxmvrla1q8lnkkq1cxv9pm75-systemd-247/bin/loginctl -H g4 list-sessions
SESSION  UID USER   SEAT  TTY
      1  118 sddm   seat0

     13 1000 efraim seat0 tty3
  15005 1000 efraim       pts/2

4 sessions listed.
(ins)efraim@3900XT ~/workspace/guix$ loginctl -H g4 list-sessions
bash: line 1: elogind-stdio-bridge: command not found

That said, the package definitely needs some work. The source URI is
autogenerated, we shouldn't need glibc as an input, and I'm guessing
that setting all the config directories to out would cause problems. Not
to mention the extra bits that don't add any value to Guix System.

D’oh!  How’s that possible?  We should also fix (upgrade?) elogin.

Yes, and also Marius’ copyright line should be preserved.

Tony, could you address these issues and send an updated patch?

Thanks, and sorry for the lengthy discussion.  :-)
