Subject: guix-install.sh: Run the uninstall even if already partially done
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Removing users, groups or Systemd units fails if they are already absent,
causing the uninstall script to exit. The goal here is to make the uninstall
always run entirely, whatever parts are already done.
* etc/guix-install.sh (sys_delete_build_user): Test if users and groups exist
before deleting them.
(sys_delete_guix_daemon): Test if /etc/systemd/system/guix-daemon.service file
exists before removing the matching Systemd unit.
