Description Greg Kroah-Hartman (RETIRED) gentoo-dev

When the IN_HOTPLUG env variable is used, every device in the system creates an entry in the udev database in /dev/.udev.  You can just test for the UDEVD_EVENT variable instead, which does the same thing and is automatically set by udev.  That way these extra database entries are not created.

By doing this, my usage of /dev goes from 600Kb to 150Kb.

Reproducible: Always

Full ack.
Either change it in every file of baselayout, or just add something like this to /sbin/runscript.sh:

[[ -n $UDEVD_EVENT ]] && IN_HOTPLUG=1

Or do this in the udev files that call stuff in /etc/init.d

baselayout will JUST use IN_HOTPLUG and I see no reason to change this

Fixed in udev-108-r1.
