Hi,

Ludovic Courtès <ludo <at> gnu.org> skribis:

Part of the problem is “fixed” by passing #:target to ‘run-with-store’
in ‘guix pack’, done in commit f7b5b8cd45b4560b3473dde2e6f6f20b4ff9daff
on ‘master’.

The other part of the problem is that profile hooks in
‘profile-derivation’ don’t honor #:target.

One can work around this by running ‘guix pack --bootstrap’ so that no
profile hooks are run.
