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

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 = #< type: # value: #< udev: # rules: (# #)>> --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. :-) --8<---cut here---start->8--- $ guix size $(guix system build gnu/system/install.scm) | head -10 store item totalself /gnu/store/0zajbn9q39yva4l0zzrcshlll8qikzba-linux-libre-4.19.6 236.5 236.5 21.2% /gnu/store/mdw00a2sq0qqyzqygmp9035g8r2rlslj-guix-0.15.0-8.71a78ba 345.7 182.3 16.3% /gnu/store/1lcniyxkxkh8g73zvh2gpbccvl6ggna7-locale-2.28 91.8 91.8 8.2% /gnu/store/dna8kpb00kq176rz8x69yy4j33my2q55-perl-5.28.0146.3 58.2 5.2% /gnu/store/ybglr7nfs8v9kpnm8vf4drg3gafnvd15-guile-static-stripped-2.2.445.9 45.9 4.1% /gnu/store/r658y3cgpnf99nxjxqgjiaizx20ac4k0-guile-2.2.4121.9 44.4 4.0% /gnu/store/9alic3caqhay3h8mx4iihpmyj6ymqpcx-guile-2.2.4121.9 44.4 4.0% /gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28 37.8 36.3 3.2% /gnu/store/4sqps8dczv3g7rwbdibfz6rf5jlk7w90-gcc-5.5.0-lib 68.0 30.2 2.7% --8<---cut here---end--->8--- Ludo’.

As discussed earlier on the list, it would be nice™ to see why these images are so big and what can be done about it. Really, 1 GiB is already a lot for such a small image. In commit 040ae1881952c90dae9478e5cfff6aad0ce950da, I ended up increasing the image size for the tests, which is not great IMO. I looked at ‘guix size’ and couldn’t find any obvious way to improve things. One problem with the installation OS is that it’s pulling ALSA and all sorts of sound-related libraries (libsamplerate, etc.), which clearly is unnecessary in the installation image. That comes from the alsa-utils udev rules. We could remove those udev rules, but since they’re in %base-services, I chose not to do that to avoid breaking everyone’s config. Food for thought! Ludo’.
