Hello,

Well I've installed Ultrix v2.2 -- and it went rather smoothly, that
is until I tried to perform backup.  I have a csh script that runs the
dump command, and it died a horrible death when I tried to run it.

During weekly and monthly backups, we shut the system down to single
user mode, sync, then perform a umount -a <--- this is the killer.
Without any warning in the release notes and with the idea to save
space on the root partition, DEC has moved /bin/csh to /usr/bin/csh
and soft linked the two.  They also did this with awk and mt.
Unfortunately I needed all of those inorder for this script to work.

I guess this letter is a warning to others who may have scripts they
run when the /usr file system is unmounted and a feeler to see how
many other people don't think this was quite right.

As an aside -- how safe is it to backup filesystems while in single
user mode without unmounting them?

Thanks
