Oops

[Darryl Hoar]

Greetings,
am setting up gmirror and screwed up my fstab.  When rebooting,
it complains until I tell it the root device:
ufs:/dev/mirror/gm0s1a

it boots up and dumps me into single user.  When I try to change
/etc/fstab, it tells me that the parition is mounted read only.

How can I get things so I can change the /etc/fstab file ?  I
looked on freebsd.org for a live cd, but didn't find one.

thanks for any help.
