Easiest way in single user if vi complains about termcap and you don't
understand ed...
As Yuri suggested:
# fsck /
# mount -ie /
Then you can just use sed in place;
# sed -i.bak -e 's,#\(.*/usr\),\1,' /etc/fstab
# fsck /usr
# reboot
Hope that helps!

Boot to single user mode (4 in the boot menu), remount / read-write -
mount -u -o rw /, edit /etc/fstab (you'll probably need to mount /usr
manually if what's in /rescue doesn't work for you), reboot.
You can run fsck from single user mode, as well.
HTH,

Re: i messed up, need to do fsck and also uncomment the /usr line if /etc/fstab
I had an old FBSD 7.2 CD. good enough for this I thought.
I booted from that but now I need to mount the file systems on my hard
drive. How do I do that?
I agree,, once I get the /etc file system mounted I can edit the file.
Okay, next..
How do I do an fsck on the /usr file system when coming up?

Boot to a boot disk.. anything... CD, DVD, USB
Load up vi - you can probably do this from a live linux distro.
Unedit the line.
Save.
Quit.
Reboot.
You're golden.

i messed up, need to do fsck and also uncomment the /usr line if /etc/fstab
Woe is me.
First, I simply messed up, happens to us all from time to time. I lost
power on an laptop running 8.2.
Restarted it but for some reason the fsck didn't run and I lost some /usr
files.
I tried to do an fsck manually but because it's mounted I got nowhere. So I
put a comment ("#") in front of the /usr line for the /etc/fstab file.
Now, I can't boot.
I need what's on my disk -- of course!
