Because it is udev that creates the device entries needed to mount /usr -
and that doesn't even touch other cases, like /usr being on a software
block device, like LVM or dmcrypt.
The problem here is that udev is trying to do too much. On the one hand
it handles the initial population of /dev/ and all that is needed to
mount the contents of fstab. On the other hand, it is trying to be an
all-encompassing device and hotplug manager. the latter function should
be started relatively late in the boot sequence, the former as soon as
possible.
I'd like to know why these functions cannot be separated, run the command
to populate /dev early on, then start the udev daemon after the
filesystems have been mounted.
Some sort of early boot rules file would need to be used to handle things
like setting up symlinks for block devices to avoid breaking some users'
fstabs.
