	Sorry: seems not explained enought: as coda administrator just did a
'cp -a' ( tar, cpio, and every variations ) and copy was fine, but when from
client try to use any command, the owner is allways "coda" and setuid
perms doesn't work. In fact, when "--preserve" option is given, get thousands
of errors like "cp: cannot restore permission XXXX on file YYYY". Seems that 
I must define all entries of /etc/passwd into list of coda users, and same 
with /etc/group entries.... but groups in coda are negative numbers... :-(

	My idea was not to define any user, just use anonymous coda login to
read and execute commands from coda's copy of /usr directory. Don't know how
to do this... even more don't know if this is possible
