Hi,

I updated guix (on guixsd) from a version from about beginning of april
to a2cfe.
After that, guix system (and other commands depending on it) give me a
backtrace.

Backtrace:
In ice-9/boot-9.scm:

gnu/system.scm:508:0: util-linux-2.31.1: unbound variable

I think it's because the older guix had a CVE fix for util-linux in
gnu/system.scm.

If that's true, what can be done to prevent this kind of breakage?

$ which guix
/run/current-system/profile/bin/guix

What's the best way to recover? I'm currently trying to build guix from
git and then reconfigure the system. Luckily I have a 'guix environment
guix -r envguix', because guix environment doesn't work neither (correct
grammar?).

Martin
