I'm setting up a new backup script that will do it all piecemeal so
that if a part of it fails, it can be retried without having to start
*everythng* over from scratch.

Which top-level filesystems should *not* be backed up.

To start with, I presumably shouldn't back up

/proc
/tmp
/dev (cause I'm using some version of *udev)
/mnt

and I certainly should back up /var, /usr. /root, /bin,
/boot, /etc, /home, /lib, /lib64, /sbin

But what about

/run
/srv
/sys
?

What are those even used for?
