bug#20255: (old)bug#20255: 'search-paths' should respect both user and system profiles

[zimoun]

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.



All the best,
simon
