ZFS and cp -x

[Daniel Staal]

have said:

> Is "cp -x" new?  Not in my 8.1 manpages.

--As for the rest, it is mine.

The online man page viewer shows it in 8.1, but not 8.0.  So, it looks like 
a gnu-ism that got brought over for 8.1, according to the manpage histories.

It's also slightly confusing in the docs: the man page only says 'File 
System mounts are not traversed'.  It probably would be worth noting that 
it only has any effect with -R, as that's the only time when you are trying 
to copy files from multiple mountpoints.  It would have cleared up for me 
that it doesn't mean you can't copy *to* a different mountpoint.  ;)
