mount option <rw> is unknown

[Randy Bush]

7-current system as of nov 27
cvsupped
removed CFLAGS and COPTFLAGS from make.conf
built and installed kernel and world

fsck ran fine
when it went to mount file systems,

    mount option <rw> is unknown
    mount: /dev/da0s1a: Invalid argument

this fstab was last touched in nov 2004, over a year ago

had to do 

    /rescue/mount -u -w /dev/da0s1a /

and so on for all filesystems.  then had to comment out fstab
so i could go multi.

wtf?????
