Re: Release!

Hello!

Time flies, but I think we’re about ready for the release.  I’d like to
aim for next Tuesday (Dec. 5th) and fix small hickups and annoyances by
then, particularly regarding GuixSD installation.

There’s more going on on the Guile side, but for now the recent split of
the big package files has helped reduce peak memory consumption
noticeably.

This was also showing up a lot in ‘guix system init’ et al, when
compiling modules.  I think a912c723f76d9762072ce27204a9227a64bcb625
removes most of these.

Yes.  Questions:

  1. Do we pre-register berlin’s key on GuixSD?

  2. Do we add berlin.guixsd.org to the list of substitute servers on
     GuixSD?  On Guix?  The drawback is that ‘guix’ sometimes talks to
     both servers when retrieve substitute lists, which can be slightly
     slower/annoying, but otherwise I think it’s a win.

Thoughts?

The main GuixSD annoying messages that I think we should address by
Tuesday are:

  1. “Error in finalization thread: Bad file descriptor” coming from the
     Shepherd;

  2. “udevd[304]: RUN{builtin}: 'uaccess' unknown /gnu/store/q7c8yayywf76ai3sgvz16pmbz07gj4bp-udev-rules/lib/udev/rules.d/73-seat-late.rules:15”

Both are harmless but they may give users a false sense that something’s
broken.
