Thanks Glynn, and Roger, for the info..
It makes sense that the source partition should be mounted RO- I guess I
was more curious about the target partition being unmounted. If it's
unmounted you can do a dd. But if you tar, (like in the bash script), it
has to be mounted, doesn't it? (dd is at the device level, tar is not?
Am I right?)
On another note, I got all new messages on this(ese) lists today as
single instances, while your replies (from Glynn Clements and Roger)
both had duplicates! Not a problem for me, but what's causing this?

You know Smithers, it's ironic. That family of
slack-jawed troglodytes cost me the election,
but if I were to have them killed, *I* would be
the one sent to jail. That's democracy for you.
