to mingetty.

Reported by Tobias Geerinckx-Rice <me@tobias.gr>

note about having the dependencies available.

Previously, entries for 'guix.fr.info' would end up in 'dir', above the
'guix.info' entries; consequently, running 'info guix' would actually
open 'guix.fr.info', which was confusing for non-French readers.

* guix/profiles.scm (info-dir-file)[glibc-utf8-locales]: New variable.
[build](info-file-language): New procedure.
(install-info): Use it, to create 'dir.LANG' files.

This reverts commit 24420f5f.

This broke 'package-transitive-supported-systems', which would return
the union of supported systems instead of the intersection.

This fixes a regression introduced in
df2f6400: since the new
'register-path' (actually 'reset-timestamps') would make files
read-only, 'delete-file-recursively' would fail to delete them.  Thus,
re-running 'guix system init' on an already-populated store would fail
with a 'delete-file' EPERM.

* guix/scripts/system.scm (copy-item): Use 'lstat' instead of
'file-exists?'.  Call 'make-file-writable' on each directory below
DEST.

* guix/ui.scm (delete-file): New error-reporting wrapper.

* guix/store/database.scm (reset-timestamps): Use 'utime' with
AT_SYMLINK_NOFOLLOW for symlinks.
