Looking at file /usr/share/doc/setup-*/uidgid on RHEL7, I can see some lines containing -, ? or number in parentheses:



...
nslcd 65 (55) / /sbin/nologin nslcd
wine - 66 - - wine
...
listar ? ? ? ? listar
...


Meaning of ? and - can be somehow implied, but what about the numbers in parentheses?



For example, what does (100) mean for games user, given users group has UID 100?



games 12 (100) /usr/games /sbin/nologin setup
users - 100 - - setup


Or better—is there an official explanation of the syntax?

          The (100) seems to be assigning the default group of the user in /etc/passwd:



          $ grep games /etc/passwd /etc/group
          /etc/passwd:games:x:12:100:games:/usr/games:/sbin/nologin
