This doesn't happen under FreeBSD.  Did you see it under System V?  In
any case, this (traditional) method of copying is no longer
necessary.  cp has an -R option which says "recursively copy
subdirectories", so instead of 

  (cd /usr/local; tar cf - .)|(cd /mnt; tar xfv -)

you can write

  cp -pR /usr/local /mnt

The -p option has the same meaning as with tar: keep the original
permissions.

I've seen too many people shoot themselves in the foot with sysinstall
on a running system.  There's another message floating around in
-questions at the moment which says that it core dumps.  What we
desperately need is a 'diskadd' program which bases on sysinstall, but
which performs appropriate checks and functions for a running system.
Unfortunately, nobody's got round to doing it yet.

I wrote a new section on using disklabel for "The Complete FreeBSD",
and somebody has offered to change it to HTML.  I suppose I should
tidy up the text and give it to him.  Watch this space.
