Phenomena: there is udev warning in boot process
tar: can't open '/etc/dev.tar': Read-only file system
The reason is that the init script /etc/rcS.d/S04udev will try to tar the /dev as cache to speed up udev at next boot time. Unfortunately, S04udev is too early and the filesystem is not writable yet.
To fix it, this patch split the cache action to another init script, and register it as /etc/rcS.d/S36, which is after the S35mountall, and the filesystem is already writable.
