Re: udev or mdev?

This.

Question: Why would I replace a known system to a unknown one? The 
effort required to replace udev with mdev could be used to create an 
initramfs to mount that /usr , or alter the /etc/init.d/udev-mount to 
depend on an extra service, which does nothing else, but mount /usr . 
With the latter, further upgrades would just need to keep the extra 
depend in the init script, long live config-protect.
