** Description changed: [Impact] Ubuntu Core has a read-only /etc, but a writable partition in /etc/writable. In some versions of Ubuntu, the systemd package ships a patch to follow symlinks from /etc/ -> /etc/writable, e.g. for files like /etc/locale.conf. In Core24, this patch needs to be expanded for /etc/locale.conf and /etc/vconsole.conf in systemd-localed. [Test Plan] - TODO + 1. On a pristine Ubuntu Core system, run "localectl status". Verify that + the system locale is set to the default (seems to be "C.UTF-8" based on + the current core24 snap). + + 2. Modify the system locale by running "localectl set-locale + LANG=en_AU.UTF-8". The command should complete without error. + + 3. Check that the locale has changed by running "localectl status". + + 4. Check that the locale has been saved to /etc/locale.conf + + 5. Reboot the system, and run "localectl status" again to check that the + change has persisted. [Where problems could occur] This hack is designed to be a no-op in non-Ubuntu Core cases. I.e., when /etc/writable does not exist or does not have a link for the given path in etc, the original path is used. As is evident by the ever-expanding nature of this patch, this is not a complete solution. It's possible that more cases will be found where this hack needs to be applied. [Other information] This patch is not carried in supported releases newer than Noble. While this patch is far from ideal, expanding this hack has become the go-to for existing stable releases.
