"Localed is a tiny daemon that can be used to control the system locale
and keyboard mapping from user programs. It is used among other things by the
GNOME Shell. The @command{localectl} command-line tool allows you to interact
with localed. This package is extracted from the broader systemd package.")

View file

@ -0,0 +1,322 @@
Normally localed would do an approximate parsing of the Xorg config file
to determine the XKB keyboard layout. This doesn't make sense on Guix
where there's no such file in /etc, and where the keyboard layout is
known statically at configuration time.
This patch removes the XOrg configuration parsing and expects to read the
configuration from environment variables instead. It also removes the
stateful bits that would write configuration to /etc/vconsole.conf
and /etc/X11, which are unused in Guix anyway.
Patch by Ludovic Courtès <ludo@gnu.org>.
