Doubtfull. Two drives currently mounted, / is ext4, and /amandatapes is

I have 3 sshfs mounts of other computers, but given the power outages, 
they could not have been mounted as thats in my /etc/rc.local and only 
mounted when this machine is rebooted. I may have had up to 3 ssh -Y 
sessions that wasn't in active use at the time of the ups shutdown.

So do I, after a 2 install foray into reiserfs long before it was ready 
for everyday use. At least a decade back.  And I need to see what it 
takes to convert the ext3 amanda uses to ext4.  That just shows how long 
I have been using amanda. It was ext2 only back in the late 90's. :)

Its empty on both drives.  So I am scratching my head yet.
