useradd-staticids: don't create username-group if gid is specified
Adding distcc to an image, and having staticids enabled,
doesn't work as it causes a a superfluous 'distcc' group
being added using a conflicting GID, thus failing the
build:
| ERROR: distcc-3.2-r0 do_prepare_recipe_sysroot: distcc: groupadd command did not succeed.
Compared to other recipes, the distcc recipe only
specifies --gid for the primary group, and doesn't specify
--no-user-group, but when --gid is given, it doesn't make
sense to create a matching username-group in addition,
even if --no-user-group was not specified, and 'useradd'
actually complains if --gid and --user-group are given
both.
If only --gid is given, the current code in here
effectively behaves as if --user-group was specified,
taking the group-id of the username-group from the
--gid parameter. This causes the error above, as we try
to add a new group (distcc) with an existing group-id
(nogroup).
This is contrary to the comment in this file just above,
contrary to what useradd can do, contrary to behaviour
without the useradd-staticids bbclass, and non-intuitive.
Change the code such that a username-group is only created
- if a primary group using --gid was not specified, or
- if --no-user-group was not specified
To be in line with useradd, if gid is not given, and
--no-user-group is given, we add the user to the group
'users', which mimics useradd's behaviour.
