Hi George,

I believe it is straightforward, as for other programs with non-default
multiple profiles: if the etc/profile is sourced, behave as if it were
the default.

I'm not sure that's related, .emacs is in the user's home.

Which shell?

The `emacs' you run is the last one in your PATH.  This is defined by
the load-order of the profiles, as for any program.  This is not Emacs-specific.

As above, this is the user's file, this is related to the Guix profile.

I believe we are talking about slightly different things.  Every user is
free to write their custom scripts and Emacs config to suit their needs.

The problem I'm trying to address here is that of the default behaviour
of non-default profiles (actually: profiles in general).  With
zero-config, zero-script.  I believe Emacs should behave like the rest,
i.e. load the packages of all active profiles.

Cheers!
