Why would you remove this?
I'd rather still have it, or extend it, maybe through an addition config
for guix system vm.. like:

guix system vm --with-net --with-forward 20:2222

would create a vm with -net user and the appropriate line to forward
port 20 of vm to port 2222 of host

and "guix system vm --without-net" could create one without?

The comment is misleading, I think a better one is:
  allow home directories to be created under /var/lib.

Also, it's better fit in the 'add-user' procudere, before
the run of `useradd' command.  And instead of handing
this particular case, how about create any parent directory
of HOME?  like:

[...]
  ;; create the parent directory of HOME.
  (when home (mkdir-p (dirname home)))

Re: [PATCH 1/9] system: vm: Remove -net user flag.

[David Craven]

You can add custom qemu flags by running $(guix system vm *.scm) -net
user. As it is now there is no way to remove it, and I've said
multiple times that it causes networking difficulties. Adding it isn't
a problem. I think that the default qemu flags should be the minimum
common denominator, and not include anything that could cause problems
in a different setup.

Your suggestions for new guix system vm flags are additional code that
has to be maintained. I don't think we need them. Besides are you
offering to implement them? Because I'm not ;-)

I don't know the behavior of activation when reconfigure services,

And to put files to /etc, it's better to extend the `etc-service-type'.

I agree, if it is a problem it should be removed.
Okay, is this documented that one can add qemu options after the
file.scm? `guix system vm --help' doesn't show it, I haven't looked at
documentation.

It's not a feature of guix system vm but of the qemu script.

$(guix system vm) evaluates to the qemu-run script then we are passing
the additional qemu flag to the script.

Apparently I need this if I want to extend git-service (ie: ssh to user
git), and for gnunet-service which requires some directories to be
present in $HOME which normally are there for users as far as I remember.
[PATHS]
SERVICEHOME = /var/lib/gnunet is not working. I could of course create
.config to ~maybe~ satisfy it, but I find this patch useful, as it will
allow me to write less code.

I briefly thought about it and thought that we should discourage users
to pick *any* home directory. This will prevent them from doing so.
But it's just an artificial restriction. In that case it's a bug fix

Indeed.

Agreed.

However, it’s even better to avoid populating /etc altogether; ideally
/etc should contain only global configuration files, such as
nsswitch.conf.

Could you instead pass the configuration file via a command-line option

I sympathize with this; what problems are you referring to?

The reason for “-net user” is that it allows me to run “dhclient -v
eth0” in the VM and get access to the network, which is often what I
want.

Now I don’t feel strongly about it, and indeed, I can always add “-net
user” on the command line.

I usually have the need to add my own flags most of the time anyway.

Is this ok as a description? I don't think the term display server is
commonly used for wayland compositors, so I left the synopsis.

    (description "Weston is the reference implementation of a Wayland

A Wayland compositor allows applications to render to a shared offscreen
buffer using opengles.  The compositor then culls the hidden parts and
composes the final output.  A Wayland compositor is essentially a
multiplexer to the KMS/DRM kernel devices.")

I renamed xwayland to xorg-server-xwayland and added cairo-xcb to
gtk.scm, xorg-server-xwayland to xorg.scm and weston to

It is bound to the global variable ‘sddm’, which is not what you want

So maybe you should have:

  (faces-directory … (default #f))

Re: [PATCH 9/9] gnu: Add weston.

Pushed. but just realized now that I should have pushed to
core-updates, since it requires patches from core-updates. Most builds
will probably fail until core-updates is merged... Sorry about that.

This failed to build on hydra:

  https://hydra.gnu.org/build/1467506  (x86_64)
  https://hydra.gnu.org/build/1467476  (i686)
  https://hydra.gnu.org/build/1467551  (mips64el)

It fails in ./configure, with the following error:

  configure: error: Package requirements (egl glesv2 wayland-client wayland-egl) were not met:
  No package 'wayland-egl' found

Did you test this?
