My system installation script (similar to install.site, run right after the
system was installed, and before first boot) attempts to configure a user
account using sometime pretty much like this:
/usr/sbin/useradd -mv -b /home -c "name of user" -u 2002 -g wheel -s
/bin/ksh -p 'encrypted-password' foo
When I did this, it created the user, but did not add the user to the group
wheel.
Based on the man page, I was expecting the -g option to do so:
useradd -D [-b base-dir] [-e expiry-time] [-f inactive-time]
[-g gid | name | =uid] [-k skel-dir] [-L login-class]
[-r low..high] [-s shell]
useradd [-mov] [-b base-dir] [-c comment] [-d home-dir] [-e
expiry-time]
[-f inactive-time] [-G secondary-group[,group,...]]
[-g gid | name | =uid] [-k skel-dir] [-L login-class]
[-p password] [-r low..high] [-s shell] [-u uid] user
-g gid | groupname | =uid
sets the default group for new users.
But it didn't, the user was created with gid 0.
When I changed the above command to use -G instead of -g, it worked. Why?
Am I just not understanding the documentation for useradd?
