Okay, sounds good.

One thing in particular about using `guix environment --ad-hoc' that is
particularly unfortunate with how I'm abusing it is that it will build
new derivations as necessary (as it is supposed to).  So "starting
icecat" in a container isn't just that.  I recently upgraded Guix, and
icecat isn't available on Hydra yet, so I'm unable to start icecat at
all until it compiles, which is hours on an X200 (though I'm assuming
that reverting ~/.config/guix/latest might allow me to work around it
temporarily with an old version).  This would not have been a problem
with a normal icecat installation in my profile.

Obviously the desirable behavior is to just containerize whatever is in
your profile, if possible.  Maybe the script you sent me does just
that.  I'm excited to play around with it, I just can't atm. :(
