Well, we still need to be able to install locales somehow, right?  :-)

‘guix-command’ in (guix self) creates a ‘guix’ binary where GUIX_LOCPATH
points to ‘glibc-utf8-locales’, always.  That means that ‘guix pull’
returns a ‘guix’ program that works fine, provided you use one of the
locales in ‘glibc-utf8-locales’ *or* you have installed ‘glibc-locales’
and set ‘GUIX_LOCPATH’.

The ‘guix’ binary of the ‘guix’ package does something similar.

These two should already eliminate most problems.  Now, we should
investigate actual problems to see why they show up precisely (for that
we need to see the output of commands, the contents of the .service
file, and so on).  That will allow us to determine the best course of
action.

As for ‘glibc-utf8-locales’ vs. ‘glibc-locales’: the reason for choosing
the former by default over the latter is size (14 MiB vs. 917 MiB).
Perhaps an improvement would be for ‘glibc-utf8-locales’ to be more true
to its name: to include all the UTF-8 locales glibc supports rather than
an arbitrary sample thereof.

Thoughts?
