It depends. If you're using gtar, that runs as root, so indeed, the group shouldn't be relevent. (Avoiding important groups like root is a good idea from a security point of view, but shouldn't affect correct operation.) If you're using dump, though, amdump usually has to run in the group that owns the relevent special files (/dev/whatever). Which group that is, is system-dependent; I've seen "disk", "operator", and "sys". (Of course you could chgrp the special files instead, but that's less wise because something, e.g. a system upgrade or an automated file-permissions-fixer, might chgrp them back.) I said "amdump *usually* has to run..." because on some systems, dump needs to run as root; in that case, I don't know whether the group matters -- same reasoning as for gtar. Hmmm, maybe rundump could take care of running dump in the correct group, on those systems where that matters, instead of not being used at all on such systems... -- | | /\ |-_|/ > Eric Siegerman, Toronto, Ont.
