Hello!
As janneke reported earlier today, wrappers generated by ‘guix pack -R’
(or ‘-RR’) swallow the program’s exit code when running in user
namespace mode:
--8<---------------cut here---------------start------------->8---
$ mkdir /tmp/pack
$ (cd /tmp/pack; tar xf $(guix pack -R sed -S /bin=bin))
$ unshare -mrf sh -c 'mount -t tmpfs none /gnu; /tmp/pack/bin/sed --whatever'
/tmp/pack/bin/sed: unrecognized option '--whatever'
[...]
$ echo $?
0
$ guix describe

branch: master
commit: bad368b0d794689f3a8a11b58f1ea4987938682e
--8<---------------cut here---------------end--------------->8---
(The ‘unshare’ trick, also used in ‘tests/guix-pack-relocatable.sh’,
allows me to pretend there’s no /gnu/store on my machine.)
