Of course it has to work, no argument here.  :-)

However, it is stateful, which makes it easier to get into troubles (for
instance because a stale .scm file remains available, so ‘guix package
-A’ would show its contents, or because of obscure timestamp issues on
existing files, particularly if one tries
“make install INSTALL='install -C'”, etc.)

Right, the model with “guix pull” is that each user is responsible for
updating their local Guix.  From the sysadmin’s viewpoint, this is bad,
because each user could have their own thing, and some could still be
installing old packages with security issues.  From the user’s
viewpoint, it’s total freedom.

Perhaps “guix pull” could honor sysadmin-handled updates, for those
cases where users do not want to run “guix pull” by themselves.  Say,
‘guix’ would look for ~/.config/guix/latest first, and then
/var/guix/latest.  Thoughts?

Sure.

Thanks,
