Public bug reported:
On focal, I cannot reload charybdis from the init script (or from
'service' or 'systemctl'):
$ sudo SYSTEMCTL_SKIP_REDIRECT=1 bash -x /etc/init.d/charybdis reload
(...)
+ start-stop-daemon --stop --signal 1 --quiet --pidfile
/var/run/charybdis/ircd.pid
start-stop-daemon: matching only on non-root pidfile
/var/run/charybdis/ircd.pid is insecure
According to start-stop-daemon(8):
-p, -pidfile pid-file
(...)
Warning: using this match option with a world-writable pidfile or
using it alone with a daemon that writes the pidfile as an unprivileged
(non-root) user will be refused with an error (since version 1.19.3)
This can be worked around by adding an --exec match to the invocation of
start-stop-daemon in do_reload() in /etc/init.d/charybdis:
start-stop-daemon --stop --signal 1 --quiet --pidfile $PIDFILE
--exec $DAEMON
