} IIUC, those uids/gids must be referred to by symbol (user/group

} I'm not sure what else have to be assured, thus asking here.

     You could possibly do it by number, but that would be foolhardy
since that would mean that you're dependent on the existing unknown
configuration of the system.  Using symbols means it doesn't matter
what the numeric value is on any given system.  And, if the symbols
don't exist then the INSTALL script can call {user,group}add (or
whatever is appropriate for the target OS) to create them.
