[PATCH 01/11] multipathd.service: add dependency on systemd-udevd-kernel.socket

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Martin Wilck <mwilck@xxxxxxxx>

Since f42d918 ("multipathd: Remove dependency on
systemd-udev-settle.service"), multipathd has no dependencies on
udev any more. In reality, multipathd depends quite heavily on udev.

multipathd startup succeeds indeed if udevd isn't running. Connecting to the
udev monitor netlink socket works, too, and if udevd is started later on,
multipathd will receive events over this socket. multipathd doesn't connect to
the udev control socket, but it does attempt to trigger uevents using
sysfs. For these events to be processed, the udev kernel socket must be
listening. For that, it's sufficient to depend on systemd-udevd-kernel.socket,
which will start udevd on demand if it isn't running.
