Summary

Creates a default group for all users of a workspace. Creates the group, add all regular users to it, and ensures that new users are also added to it.

Requires

Debian/Ubuntu operating system.

Description

1. Adds the group with the desired name and gid.
2. Modifies /etc/security/group.conf so that the group is added by PAM whenever a user logs in.
3. Takes all existing regular users and adds them to group.
4. Adds the group to the EXTRA_GROUPS instruction in /etc/adduser.conf so that new users created with /sbin/adduser (a Debian/Ubuntu tool, not to be confused with useradd) are automatically added to the new group.

• also ensures that existing groups in EXTRA_GROUPS are kept. On SRC workspaces, this includes the davfs2 group by default.

Variables

• dict default_group_group:
  • default_group_group.groupname: name of the group to create
  • `default_group_group.gid``: # optional. gid (numeric) of the group
