Hi!

Efraim Flashner <efraim <at> flashner.co.il> skribis:

Oh.  I was conservative and thought that people would rather use
“standard” tools.

The comment is still correct: “guix container exec” is more verbose.
:-)

Should we change it so that “guix container exec PID” without additional
arguments runs /bin/sh by default, or something like that?
