Hi Garjola!

Which mad-Max manual indicates this?  Not [my copy of] Guix's:

  “(1) Users sometimes wrongfully augment environment variables
  such as 'PATH' in their '~/.bashrc' file.  As a consequence,
  when 'guix environment' launches it, Bash may read '~/.bashrc',
  thereby introducing "impurities" in these environment variables.
  It is an error to define such environment variables in
  '.bashrc'; instead, they should be defined in '.bash_profile',
  which is sourced only by log-in shells.
  *Note (bash)Bash Startup Files::, for details on Bash start-up
  files.”

	-- info "(guix)Invoking guix environment"

Adding PATH to .bashrc is almost always a mistake, and round that 
up to ‘always’.  As a Guix System user I'm less familiar with 
GUIX_LOCPATH, but the manual doesn't suggest adding it either.

> Actually, despite the configuration in .bashrc

Side note: sourcing <profile>/etc/profile configures your 
environment to ‘see’ Guix-installed software.  It does not 
configure Guix, which will install to ~/.guix-profile unless you 
specify another one with --profile= (-p).

Lo:

  ~ λ ls -l ~/.guix-profile
  lrwxrwxrwx 1 nckx nckx 45 Sep 28 09:01 /home/nckx/.guix-profile
	-> /var/guix/profiles/per-user/nckx/guix-profile/

Unless something has gone *very* wrong, your installed packages 
should show up under both /var/... and ~/.guix-profile alike.

This is good: ~/.config/guix/current is not ~/.guix-profile.

The latter is your default profile, where ‘guix install’ and 
friends install software.  The former is exclusively for use by 
‘guix pull’ and provides the ‘guix’ command itself, to avoid a 
chicken-and-egg problem.

> The most annoying thing is that the programs are not in the path

I don't want to presume what you mean: that they're not where you 
thought they would be (not in ~/.config/guix), or that you can't 
actually run them (not in PATH)?

There's nothing wrong with any of the directories you mentioned. 
If you can run Guix-installed software from the shell immediately 
after installing it, I'd say that the /var thing is just a quirk 
of running Guix on a foreign distribution.

Quite a few regulars do so, some on Debian.  I'll let them correct 
me if I'm wrong (and explain the mystery that is GUIX_LOCPATH).

Kind regards,

T G-R
