To use mdev, the proc and sysfs filesystems must be mounted


mdev must be enabled as the hotplug event manager

echo /sbin/mdev > /proc/sys/kernel/hotplug


Need to mount /dev as a tmpfs:

mount -t tmpfs mdev /dev


Tell mdev to create the /dev entries corresponding to the devices detected during boot when mdev was not running:

mdev -s


The behavior is specified by the /etc/mdev.conf configuration file, with the following format

<device regex> <uid>:<gid> <octal permissions> 

[=path] [@|$|*<command>]


Example

hd[a­z][0­9]* 0:3 660
