apparently there are 2 init scripts concerned with some "udevd":
/etc/init.d/eudev
/etc/init.d/udev

The second belongs to initscripts and is a gift from debian that
should be disabled by not having /lib/systemd/systemd-udevd

The first, which for me is the S02 link, is the one in use.

Sometimes that takes time, for example when it involves network
configuration (due to some allow-hotplug declaration) and the DHCP
response is slow, but alos other reasons.

To trace udevd, you may need to instrument the init script with a
"udevadmin monitor 2>&1 &" or something similar.
