Dear, What is the status of the bug#20255 [1]? It is old; the last activity seems back on 2015, November. So let resume. The issue is, e.g.: - perl installed into the system profile - perl-xml-parser installed into an user profile Then "guix package --search-paths" does not set correctly XML::Parser. Fixes had been pushed: dedb17a and b2a7223 and cc3de1d. The final fix is still missing. Because it is a controversial patch [2] :-) i.e., running 'guix' in '/etc/profile'; see these lines of the patch: --8<---------------cut here---------------start------------->8--- + eval `/run/current-system/profile/bin/guix package \\ + -p /run/current-system/profile \\ + -p \"$HOME/.guix-profile\" --search-paths` --8<---------------cut here---------------end--------------->8--- The friendly "protest" [3] is about turning these lines optional via an environment variable. I am not sure to follow where the discussion had been going then. Well, is the issue still happening 4 years later? If yes, what should be the fix? What is the status quo? If no, let close the bug. Note that other patches are still pending [4] and [5] -- probably irrelevant now.
