mdev
mdev [-s]
-s Scan /sys and populate /dev during system boot
It can be run by kernel as a hotplug helper. To activate it:
echo /bin/mdev >/proc/sys/kernel/hotplug It uses /etc/mdev.conf
with lines [-]DEVNAME UID:GID PERM [>|=PATH] [@|$|*PROG]
What mdev probably is missing is libudev which some programs whishes to
use.
/proc/sys/kernel/hotplug is missing in debian & devuan kernel since some years
now. Is there a way (despite recompiling) to get it back?

Busybox, as from version 1.24.1, has a netlink listener meant to
fork mdev (or any other app) on uevents. This is meant precisely to
emulate hotplug behaviour in case it is disabled in kernel. The applet
is named "uevent" . https://www.busybox.net/
Nathanael Copa has considered transforming Mdev so as to read the
netlink - together with other improvements. This has some advantages,
such as not needing dirty tricks to serialize the processing of uevents.
The advantage of keeping Mdev as it is now is that it is not constantly
running (and consuming ressources) while it is rarely working except at
startup; this maybe important on tiny systems.
