The only way i understand how to trivially get a precise environment is
"guix environment --pure --ad-hoc package1, package2, ... packageN"

Don't options #2 and #3 also include everything from the default profile
and system profile?

I like the ability to maintain separate profiles and run "guix upgrade
-p my/profile" on each profile, but I haven't figured out how to get
something equivalent to "guix environment --pure --profile my/profile".

I find this useful when updating diffoscope or reprotest packages, which
tend to have a lot of suggested optional packages that aren't really
hard dependencies.

This looks "load-profile" subcommand seems to attempting to meet that
use-case, if I'm reading it correctly?


live well,
