yeah sorry about the ee thing for some reason it is
not in the rescue directory only vi is which will
work, but not my favorite editor. to get ee you would
have to mount /usr and its in /usr/bin if I'm not
mistaken. you might have to use absolute paths to get
programs to run like "/usr/bin/ee /etc/fstab" or
"/rescue/vi /etc/fstab" if your gungho about things.
as for the mount error that is odd. did you check the
output of just a plain
if it tells you root is mounted r/w which I think
would be so unless it says readonly then you don't
have to worry about that step. Bur single user mode
always puts root in readonly. I haven't experienced it
puking during boot because of a bad line in fstab
though so I am not certain how that works.
Your best bet is probably to boot from the FreeBSD
install disk, run Fixit shell from the CD/DVD-Rom
/dist/sbin/mount /dev/ad0s(insert your bsd slice \
then run ee /mnt/etc/fstab
I don't think the absolute paths to everything is
necessary, but I'll give them anyway to cover the
note if your want to mount that msdosfs for whatever
reason you have to do this
/dist/sbin/mount_msdosfs /dev/ad0s5 /foobar
I've had to deal with that little problem before.
the fixit shell does not load all the kernel modules
you might need only a subset, and mount -t msdosfs
doesn't seem to work anytime I try it so that one
REQUIRES the absolute path to work.
