Do you still have a vetted interest in the issue at hand?  This is a
serious usability problem that's been in limbo for 6 years, apparently
for reasons of purity (not wanting to run a command in /etc/profile).
While I share the sentiment that /etc/profile would better be 'inert' or
static, it seems we haven't been able to come up with a better solution
than calling 'guix package --search-paths'.  Like Ludovic, I also don't
find the idea of allowing users to override /etc/profile very appealing;
even if undocumented, its mere presence in the operating-system field
would be an invitation for problems.  An environment variable to disable
such basic functionality also seems backward to me.

I would personally be in favor of committing the fix as-is.  If < 1 s of
wasted time on boot is an issue, I suggest to look into GNU Shepherd to
offset it; optimization opportunities should abound :-).

Thank you,

Maxim
