Mind the _re_-mount,
if udev discovers /dev not being mounted, udev does.
if udev discovers /dev mounted, no mount action is taken.
Earlier versions remounted /dev regardless.

My best practice is to have CONFIG_DEVTMPFS_MOUNT enabled:
I don't use initrd (except for disk encryption) and
I still find my disks during init=/bin/bash recovery.

and it does not hurt, anymore.
