Hi
The manual reads:
"This |~/.config/guix/current| profile works like any other profile
created by |guix package| (see Invoking guix package
<https://www.gnu.org/software/guix/manual/en/html_node/Invoking-guix-package.html#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 --roll-back
switched from generation 3 to 2
$ guix package -p ~/.config/guix/current --delete-generations=1
deleting /home/charlie/.config/guix/current-1-link"
Users without a working guix is not helped by this.
Ie they get errors when trying to run guix package -p ...:
"Missing guile-gcrypt bla bla"
I suggest a note below this saying:
"Note: if your have wound up with a faulty guix after a "guix pull" you
can manually run an older version by looking at the symlinks in your
/user/home/.config/guix/ directory.
E.g. if it lists:
$ ls -l /root/.config/guix/
total 0
lrwxrwxrwx 1 root root 33 Nov 4 01:24 current ->
/root/.config/guix/current-1-link
...
Then your faulty guix is in current-1-link, and your former probably
well working guix is in an older symlink, e.g. current-2-link.
To run the guix-version before the last pull in the example above, run:
/root/.config/guix/current-2-link/bin/guix
Now go ahead and use that older guix to roll back as described above."
What do you think?
