mdevd

What is it ?

mdevd is a small daemon managing kernel hotplug events, similarly to udevd.

It uses the same configuration file as mdev, which is a hotplug manager integrated in the Busybox suite of tools. However, mdev needs to be registered in /proc/sys/kernel/hotplug, and the kernel forks an instance of mdev for every event; by contrast, mdevd is a daemon and does not fork.

The point of mdevd is to provide a drop-in replacement to mdev that does not fork, so it can handle large influxes of events at boot time without a performance drop. mdevd is designed to be entirely compatible with advanced mdev usage such as mdev-like-a-boss.

Comparison with mdev -d

Recent versions of mdev have a -d option that allow it to run as a daemon. However, mdevd still has advantages over mdev -d:
