Hi Guix,
An unfortunate chain of propagated-inputs causes 'util-linux' (mount,
umount, etc.) to be installed alongside 'mps-youtube': 'mps-youtube'
propagates 'python-pygobject', which propagates 'glib', which propagates
'util-linux'. It seems to have been introduced with commit 6c237a2,
when 'util-linux' was moved to the propagated-inputs of 'glib'.
This is a problem on foreign distributions, where the stowaway 'mount'
and 'umount' commands installed by Guix shadow the setuid ones provided
by the distro.
I am currently on commit ecf3a3a (post core-updates merge).
Regards,
Diego

I have attached a WIP patch that fixes this "long term", by moving the
util-linux libraries to a separate output. It rebuilds 7753 packages
and is intended for the 'core-updates' branch.

Subject: [PATCH] gnu: util-linux: Move libraries to separate output.
Fixes <https://bugs.gnu.org/37732>.
Reported by Diego Nicola Barbato <dnbarbato@posteo.de>.
* gnu/packages/linux.scm (util-linux)[outputs]: Add "dev".
[arguments]: Update #:configure-flags accordingly. Add phase
"adjust-bindirs", and rename "move-static-libraries" to "move-libraries",
while adding a substitution for the .pc files.
* gnu/packages/fontutils.scm (fontconfig)[propagated-inputs]: Use the "dev"
output of UTIL-LINUX.
* gnu/packages/glib.scm (glib)[propagated-inputs]: Likewise.

The size of 'fontconfig' (as reported by `guix size`) decreases from
103.6 MiB to 92.1 MiB with this patch. \o/
Short term I'm not sure what to do. Perhaps we can add a
"glib-sans-util-linux" variant that does not propagate util-linux? Or a
variant that propagates a util-linux-sans-binaries?
Diego: one work-around you can try in the meantime is to create a
~/setuid-programs, add it first on PATH, and symlink the required
binaries in there. Sorry for the inconvenience!

No worries. I have simply removed 'mps-youtube' from my profile and use
it with 'guix environment --ad-hoc mps-youtube -- mpsyt' instead. The
difficult part was finding out which package propagated 'util-linux'. I
used 'emacs-guix' and lucky guesses to find it (fortunately the profile
only contained 12 packages).
Is there a more convenient way to recursively show all propagated-inputs
of a given package? It would be interesting to check how prevalent this
propagation pollution is (another example that comes to mind is 'jami',
which installs 125 programs under bin/, of which only about half can be
attributed to 'util-linux').
Thanks,
Diego

Do we know why this commit moved ‘util-linux’ to propagated-inputs?
Presumably because of this line in ‘gio-2.0.pc’, right?
Requires.private: gmodule-no-export-2.0, zlib, mount >= 2.23, libselinux
If it’s “just” because of this, I’d say we don’t need to propagate
‘util-linux’: we only build shared libraries for GLib anyway, so none of
our packages actually use ‘Requires.private’. If we were to add
packages requiring it, it’s fine to just add ‘mount’ as an explicit
inputs of these packages IMO.
We could follow the same reasoning for the other things that are
propagated due to their being listed in ‘Requires.private’.
Thoughts?
Moving ‘util-linux’ back to ‘inputs’ could perhaps be done on the next
‘staging’ or on ‘core-updates’.

Shared libraries are not just for development, so I’d say it should be
“lib” instead, no?
Thanks,
Ludo’.

I assume so.

Right. You know, I had forgotten that Requires.private were for static
libraries. Thanks for pointing that out. I think quite a few packages
propagate Requires.private dependencies without using static libraries.
Something to watch out for in the ongoing quest to purge static
libraries from Guix.

util-linux now has 7880 dependent packages, as 'fontconfig' recently
started depending on it. So it must go through 'core-updates'. Luckily
that branch is slated to start by the end of this month, so the waiting
time should not be too long.

Agreed. Will adjust this patch accordingly once I get around to start
working on 'core-updates'. :-)

I opted for a more conventional "lib" output and pushed the patch to the
'core-updates' branch in bb93042c8beb881ab907fa802eefb3c4091039a2.
