bug#45599: using guix to install packages from inside a container that runs on foreign distro breaks guix and the foreign distro

[Ludovic Courtès]

Hi David,

Looks like this bug report fell through the cracks of the turn of year…

It looks as though the store item for Guix or Guile used on the host had
been suddenly wiped, even though we don’t see any GC activity or
similar.

Were you able to better see what was broken?  Is it that store items
were removed?  Are there issues with non-Guix files?  It would be great
if you could gather more details as to what’s wrong.  I’ll also see if I
can try that in a VM.

Thanks,
Ludo’.
