Hi,

as discussed on IRC [1][2] `guix archive --export` is currently broken on
foreign distributions. It fails with the error message:

	guix archive: error: corrupt input while restoring archive from #<closed: file 7f27c396e150>

strace reveals `guix authenticate` prints a message to stderr, which the
guix-daemon does not expect:

	guile: warning: failed to install locale

Installing the package glibc-locales into root’s user profile (because
guix-daemon.service references that) and restarting the daemon solves the
issue.

Cheers,
Lars
