Or we could just remove the sound services from the installation image.

for sure users should be warned of this important change, anyway I doubt
any user using sound does not use %desktop-services (possibly customized)
> I’m in favour of moving them elsewhere, such as %desktop-services.
yes please: sound related services are not-so-base, we do not need them
on installation/web/mail/DNS et. al servers (and containers) and it does
not makes much sense to remove them an all that class of
hosts/containers
it makes sense - semantically speaking - to move sound to
%desktop-services since we only need sound on desktops
thanks!

I would prefer if sound services were removed from the installation
system rather than from the %base-services. I am using systems based on
%base-services for music playback and other audio work. They are not
desktop systems — there is no graphical interface to these machines.

Yeah I do that as well.
On closer inspection my initial diagnostic was not accurate: the ALSA
udev rules are not in the installation system itself:
--8<---------------cut here---------------start------------->8---
scheme@(gnu system install)> (define s (operating-system-services installation-os))
scheme@(gnu system install)> (fold-services s #:target-type udev-service-type)
$3 = #<<service> type: #<service-type udev 2cb00f0> value: #<<udev-configuration> udev: #<package eudev@3.2.5 gnu/packages/linux.scm:2039 3cd2e40> rules: (#<package lvm2@2.02.177 gnu/packages/linux.scm:2101 3cd2cc0> #<package crda@3.18 gnu/packages/linux.scm:2237 3cd2a80>)>>
--8<---------------cut here---------------end--------------->8---
Instead, the ALSA rules come from the bare-bones OS, which we
purposefully add as a GC root of the installation OS (see commit
4e854b1814a9216ae7cc90aef4d82fd989a519c3).
So I suppose there’s not much we can do in this area.
The good news is that there are other optimization opportunities. :-)

Why does Guile 2.2.4 appear twice but with a different hash?

That’s a good question! It’s the kind of thing that we need to
investigate…
