Subject: [PATCH] units: remove udev control socket when systemd stops the
|
||
|
|
socket unit (#49)
|
||
|
|
|
||
|
|
Mere presence of the socket in the filesystem makes
|
||
|
|
udev_queue_get_udev_is_active() return that udev is running. Note that,
|
||
|
|
udev on exit doesn't unlink control socket nor does systemd. Thus socket
|
||
|
|
stays around even when both daemon and socket are stopped. This causes
|
||
|
|
problems for cryptsetup because when it detects running udev it launches
|
||
|
|
synchronous operations that *really* require udev. This in turn may
|
||
|
|
cause blocking and subsequent timeout in systemd-cryptsetup on reboot
|
||
|
|
while machine is in a state that udev and its control socket units are
|
||
|
|
stopped, e.g. emergency mode.
|
||
|
|
|
||
|
|
Fixes #2477
