Just one comment:
Having "hdc*:root:disk:660" in udev.permissions and calling "udevstart"
will always set /dev/hdc to root:disk and 600. With owner and group
fields empty, udevstart will not change the owner and the group. I'm
not sure if udevstart triggers "add" events, likely not?

With the permission field empty, udevstart will set the permissions
to 000, although udev.conf specifies 0600 as default, so I guess this
is wrong...

cu,
Frank
