patch_mate-notification-daemon.sh

#!/bin/sh
# The mate-notification-daemon in ubuntu mate is crashing frequently.
# This is caused by the function do_exit() inin daemon.c, which triggers
# exit(0); instead of gtk_main_quit() in order to stop the main process.
#
# This script fixes this. It creates a new deb package from the existing one and
# installs this subsequently. It does this in a chroot environment, preventing
# the system to get cluttered further.
#
# target system: ubuntu 24.04 (noble)
