User management improvements

Management of local users and groups (i.e. those in /etc/passwd and /etc/group) is done using the LCFG auth component. One feature that has always been lacking is the ability to create a home directory where necessary and populate it from a skeleton directory (typically this is /etc/skel). The result of this feature being missing is that it is necessary to add a whole bunch of additional file component resources to create the home directory and that still doesn’t provide support for a skeleton directory.

Recently I needed something along those lines so I’ve taken the chance to add a couple of new resources – create_home_$ and skel_dir_$. When the create_home resource is set to true for a user the home directory will be created by the component and the permissions set appropriately. By default the directory will be populated from /etc/skel but it could be anything. This means it is now possible to setup a machine with a set of identically initialised local users.

For example:

auth.pw_name_cephadmin           cephadmin
auth.pw_uid_cephadmin            755
auth.pw_gid_cephadmin            755
auth.pw_gecos_cephadmin          Ceph Admin User
auth.pw_dir_cephadmin            /var/lib/cephadmin
auth.pw_shell_cephadmin          /bin/bash
auth.create_home_cephadmin       yes /* Ensure home directory exists */

auth.gr_name_cephadmin           cephadmin
auth.gr_gid_cephadmin            755
