Hello Guix!
Here is the “new” ‘guix pull’ that we discussed notably in this thread:
https://bugs.gnu.org/22629
The major difference is that instead of just building a bunch of modules
and putting them under ~/.config/guix/latest, it now produces a
standalone package (with bin/guix, share/info/guix.info, etc.) and puts
it in a profile under ~/.config/guix/current. Quoth the manual:
The result of running ‘guix pull’ is a “profile” available under
‘~/.config/guix/current’ containing the latest Guix. Thus, make sure to
add it to the beginning of your search path so that you use the latest
version, and similarly for the Info manual (*note Documentation::):
export PATH="$HOME/.config/guix/current/bin:$PATH"
export INFOPATH="$HOME/.config/guix/current/share/info:$INFOPATH"
This ‘~/.config/guix/current’ profile works like any other profile
created by ‘guix package’ (*note Invoking guix package::). That is, you
can list generations, roll back to the previous generation—i.e., the
previous Guix—and so on:
$ guix package -p ~/.config/guix/current -l
Generation 1 May 25 2018 10:06:41
guix 221951a out
/gnu/store/i4dfk7vw5k112s49jrhl6hwsfnh6wr7l-guix-221951af4
Generation 2 May 27 2018 19:07:47
+ guix 2fbae00 out
/gnu/store/44cv9hyvxg34xf5kblf5dz57hc52y4bm-guix-2fbae006f
- guix 221951a out
/gnu/store/i4dfk7vw5k112s49jrhl6hwsfnh6wr7l-guix-221951af4
Generation 3 May 30 2018 16:11:39 (current)
+ guix a076f19 out
/gnu/store/332czkicwwg6lc3x4aqbw5q2mq12s7fj-guix-a076f1990
- guix 2fbae00 out
/gnu/store/44cv9hyvxg34xf5kblf5dz57hc52y4bm-guix-2fbae006f
$ guix package -p ~/.config/guix/current --roll-back
switched from generation 3 to 2
There are two requirements it fulfills in terms of compatibility:
1. The modified ‘build-aux/build-self.scm’ still does the right thing
when evaluated by an “old” Guix—that is, it produces a bunch of
modules for use in ~/.config/guix/latest as before.
2. The modified ‘guix pull’ produces ~/.config/guix/current even when
invoked on a commit of a past Guix. That is, it automatically
produces a ‘guix’ command using the modules returned by the old
‘build-self.scm’.
There are various improvements we can make from there. For example,
using “manifest entry properties” as proposed in
<https://bugs.gnu.org/31442>, we can attach meta-data (commit ID, repo
URL, etc.) in each manifest entry that ‘guix pull’ populates; then we
can arrange for ‘guix pull --list-generations’ (say) to display that
information.
We could add ‘guix pull’ options for convenient: ‘--roll-back’,
‘--profile’, etc.
Going forward, additional “channels” could be presented as entries in
the ~/.config/guix/current manifest.
Caveats:
1. The ~/.config/guix/current profile really lives there. That is,
unlike ~/.guix-profile, it’s not in /var/guix/profiles/per-user.
That could be an issue for cluster setups where home directories
are not scanned by the Guix GC. Cluster folks, please tell me!
2. The translated Info manual is not built. Julien: could you turn
the big ‘xref_command’ in a script or something that we can more
easily reuse in (guix self)?
3. C++ code is not built. I wonder which will come first: getting rid
of the C++ code, or building it? :-)
Feedback welcome!

pull: Install the new Guix in a profile.
self: Compute and use locale data.
