i messed up, need to do fsck and also uncomment the /usr line if /etc/fstab

[Henry Olyer]

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!
