Thanks a lot for testing and providing detailed feedback!  I think
Tobias and Marius already commented on most issues; some can be fixed
for 0.15, others are unfortunately trickier to address.

I made some adjustments to ‘guix system init’ later today, but it
shouldn’t make a big difference here.

Did you have troubles with substitutes?  In particular, did it hang as
described in <https://bugs.gnu.org/31925>?  (I’m still experiencing it
occasionally and I can’t believe I’m the only one.)

The English part comes from the C++ code base, which is not i18n’d,
whereas the other line comes from the Scheme part, which is i18n’d.

Here the Scheme code prints numbers according to your German locale;
however, there’s apparently no translation of the message itself, which
is why it still says “freed”.  Weird, I agree.

As discussed on IRC with Tobias, that’s a mistake; we should use
--color=auto.  Tobias, are you committing this change?  :-)

Thanks!
