I tried that. It seems that there is a precident to use /variant for the variable.
However / is not permitted in the name

Well I don't actually *need* to. I could have copied it. But I thought that
having 3 copies would make maintenance difficult---somebody might update one,
but forget the other two.

Sorry for not being precise enough. I meant why are us using "inherit"
here? I thought
(source (package-source util-linux/base))
would suffice and result in the same?

Do I get it right that these changes aim to make ‘mount -t nfs’ work?
That is, to allow ‘mount’ to find the ‘mount.nfs’(?) program.
If so, would it work to just do:
"--enable-fs-paths-default=/run/current-system/profile/sbin"
?
That would only work on GuixSD, but Guix’s ‘mount’ is certainly not very
useful on foreign distros.
Thanks,
Ludo’.

Do I get it right that these changes aim to make ???mount -t nfs??? work?
That is, to allow ???mount??? to find the ???mount.nfs???(?) program.
That is correct.
If so, would it work to just do:
"--enable-fs-paths-default=/run/current-system/profile/sbin"
?
That would only work on GuixSD, but Guix???s ???mount??? is certainly not very
useful on foreign distros.
That would certainly be a solution easier to do.
But doesn't it mean that we have a "functionally impure" system?

That ‘mount’ can invoke ‘mount.nfs’ looks like a convenience to me, not
something highly critical.
I would say that dynamic composition (‘mount’ looking up ‘mount.nfs’ &
co. in $PATH) is OK in this case. The NFS service in GuixSD could
extend ‘profile-service-type’ such that ‘nfs-utils’ is indeed in the
system profile.
WDYT?
Thanks,

That ???mount??? can invoke ???mount.nfs??? looks like a convenience to me, not
something highly critical.
Well it's critical if "mount -a" is going to work, and thus if NFS filesystems (such as /home in
many networks) can be automatically mounted at boot time.
I would say that dynamic composition (???mount??? looking up ???mount.nfs??? &
co. in $PATH) is OK in this case. The NFS service in GuixSD could
extend ???profile-service-type??? such that ???nfs-utils??? is indeed in the
system profile.
Ok If you think it's acceptable I'll push a change with just the
"--enable-fs-paths-default=/run/current-system/profile/sbin" option for now. If it
turns out not to be good enough then we can rethink it later.

GuixSD doesn’t use the ‘mount’ command to mount file systems so that
shouldn’t have any influence.

Yes, I agree.
1,093 packages depend on util-linux. Per the strategy outlined at
<https://lists.gnu.org/archive/html/guix-devel/2016-10/msg00933.html>
this could go to ‘staging’ but I think this should go to ‘core-updates’
which we’ll reopen to fix <http://bugs.gnu.org/24703>.

GuixSD doesn???t use the ???mount??? command to mount file systems so that
shouldn???t have any influence.
What does it use instead?

I'm irritated that util-linux has so many, completely unrelated things in it. For example
it contains the "mount", "cal" and "col" commands. Regardless of the NFS issues, I
suggest we consider separating it anyway, into several packages all deriving from the common
source.

The ‘mount’ system call; see (gnu build file-systems).

The strategy is to stick to what upstream does, in general, and I’m not
convinced splitting would buy us much (in terms of disk usage, for
instance.)

The ???mount??? system call; see (gnu build file-systems).
I confess, I have not really thought about this before. But supposing somebody has in their /etc/config.scm:
(file-systems
(cons*
(file-system
(device "my-root")
(title 'label)
(mount-point "/")
(type "ext4"))
(file-system
(device "fileserver.example.com:/home")
(title 'device)
(mount-point "/home")
(type "nfs4"))
%base-file-systems))
Would the /home filesystem then get mounted on boot?

In general I think that is a sensible strategy. Splitting, would not buy us anything
in terms of disk space, but I think it would mean less rebuilding when some configure
option needs to be changed.

Maybe not. :-)
The man page for mount(2) says:
--8<---------------cut here---------------start------------->8--- Values
for the filesystemtype argument supported by the kernel are listed in
/proc/filesystems (e.g., "btrfs", "ext4", "jfs", "xfs", "vfat", "fuse",
"tmpfs", "cgroup", "proc", "mqueue", "nfs", "cifs", "iso9660"). Further
types may become available when the appropriate modules are loaded.

Yeah, but that’s probably not a significant improvement in terms of
avoiding rebuilds.

The ‘mount’ binding shouldn’t try to be smart and do things like this
IMO. However, we could have a separate helper procedure to do that, if
needed and ‘file-system-shepherd-service’ would pick the right one.
Now, we should add system tests for that, otherwise it sounds like we’re
adding code that will rarely be used and we’ll never know whether it
actually works or how it’s supposed to be used. :-)
Thanks,

Looking at mount(8), it seems that the normal way is for ‘source’ to be
something like “knuth.cwi.nl:/dir”. The kernel then takes care of
parsing that and doing name resolution somehow.
In that case, we don’t have anything to do, good for us.
mount(8) doesn’t mention ‘addr’. Do you have documentation about it?
Thanks,
Ludo’.

Looking at mount(8), it seems that the normal way is for ???source??? to be
something like ???knuth.cwi.nl:/dir???. The kernel then takes care of
parsing that and doing name resolution somehow.
In that case, we don???t have anything to do, good for us.
Unforunately that is not the case. :(
Attempting to mount a NFS system by a direct system call will fail unless you
pass addr= as an option (try it if you don't believe me). The mount.nfs
command when used with -v shows what actually goes on:
$ sudo mount.nfs -v 192.168.0.125:/export/junk /mnt
mount.nfs: timeout set for Wed Nov 23 23:50:43 2016
mount.nfs: trying text-based options 'vers=4.2,addr=192.168.0.125,clientaddr=192.168.0.22'
mount.nfs: mount(2): Protocol not supported
mount.nfs: trying text-based options 'vers=4.1,addr=192.168.0.125,clientaddr=192.168.0.22'
mount.nfs: mount(2): No such file or directory
mount.nfs: trying text-based options 'addr=192.168.0.125'
mount.nfs: prog 100003, trying vers=3, prot=6
mount.nfs: trying 192.168.0.125 prog 100003 vers 3 prot TCP port 2049
mount.nfs: prog 100005, trying vers=3, prot=17
mount.nfs: trying 192.168.0.125 prog 100005 vers 3 prot UDP port 45585
192.168.0.125:/export/junk on /mnt type nfs
As you can see, it does a kind of crude protocol negotiation with the server.
It's also instructive to experiment a bit by running a command like:
sudo strace mount -v :/export/junk -o addr=192.168.0.125 /mnt
in which one can see the system call:
mount(":/export/junk", "/mnt", "nfs", MS_MGC_VAL, "addr=192.168.0.125") = 0
However running the same command but dropping the option will result in:
sudo strace mount -v :/export/junk /mnt
mount(":/export/junk", "/mnt", "nfs", MS_MGC_VAL, NULL) = -1 EINVAL (Invalid argument)
So I think we really do need this patch or something similar to it.
mount(8) doesn???t mention ???addr???. Do you have documentation about it?
This aspect of NFS is poorly documented. The best I found is a discussion at
http://stackoverflow.com/questions/28350912/nfs-mount-system-call-in-linux

Could we write it as:
(if (string-prefix? "nfs" type)
(mount-nfs source mount-point type flags options)
(mount source mount-point type flags options))
and have a separate:
(define (mount-nfs source mount-point type flags options)
…)
?
Also, the code above must be changed to use ‘match’ instead of ‘car’.
It should be (getaddrinfo host "nfs") instead of (getaddrinfo host #f).
I’m assuming the syntax for SOURCE doesn’t allow one to specify a TCP
port. Is this correct?
Thanks,
Ludo’.

Looks like you forgot to address some of suggestions I made

number?):

Looks like you forgot to address some of suggestions I made

Ok. I will make that change.
???match???,
Have another look: + (let* ((host (match (string-split source #\:) ((h _) h)))

Sorry. The answer is, no so far as I'm aware, there is no convention which
allows a port number to be specifed in the source field.

The only other thing I think you mentioned was using "if" instead of "cond".
I can envisage that in the future there will be a need for other cases, -
it's not just an either/or choice - so it seemed to me that cond was more
appropriate.
I am aware there is room for improvement in this patch (for example in the
case of IP6 addresses?) - any help will be gratefully accepted.

Right, but there are other occurrences of ‘car’ for ‘getaddrinfo’. :-)

OK (this would have changed the way ‘source’ is parsed.)

‘getaddrinfo’ can return both IPv4 and IPv6 addresses, so in theory,
the patch is IPv6 Ready.

Right, but there are other occurrences of ???car??? for ???getaddrinfo???. :-)
But that occurance applies to a real list, rather than a list used as record.
In other words, I really do just want to get the first item of that list.
As I understand it, match is supposed to be used for heterogenous lists where
each member has its own semantics. That is not the case here.
Obviously, I could write (match ... (x . _) x) but I don't see what benefit that
brings.

‘match’ can be used to match anything, and I highly recommend using it
for lists (info "(guile) Pairs"): it generates clearer and foolproof
code.
In this case ‘getaddrinfo’ might well return an empty list.

???match??? can be used to match anything, and I highly recommend using it
for lists (info "(guile) Pairs"): it generates clearer and foolproof
code.
In this case ???getaddrinfo??? might well return an empty list.
So then "car" would raise an error (unless I check it first with pair?) - just
as match would raise an error unless I add a catch-all case. I'm still not
convinced that match has any advantages in this case.
However I've changed it despite that, and pushed this patch to master. I hope
it's ok.

No big deal, but it’s not what I meant.
An expression like:
(let ((x (match lst1 ((a . b) a)))
(y (match lst2 ((a . b) a))))
…)
is almost equivalent to using ‘car’ twice, only more verbose. That is,
the cases where ‘lst1’ or ‘lst2’ is empty are not handled (‘match’
raises an exception.)
The real gain is when each case is explicitly separated and handled:
(match lst1
((x . _)
(match lst2
((y . _)
(do-something x y))
(_
(error "lst2 is empty"))))
(_
(error "lst1 is bogus")))
In this case we’d want to gracefully handle syntax errors in ‘source’
and host name lookup failures for instance.
