| ## stateless systems (note) ##
| |
| A lot of work is being done here on stateless systems - aka bootup with minimal configuration. look into that, talk to systemd maintainers to see if this functionality exists in a marketable state.

| ## systemd-sysusers creates system users on demand ##
| |
| A new tool, `systemd-sysusers`, can be used to create system users and groups on startup. On startup, the `systemd-sysusers` service reads configuration files in /usr/lib/sysusers.d/, which are provided by packages or adminstrators, and creates the relevant entries in /etc/passwd and /etc/groups.
| |
|
| |
| These configuration files can be used to create users, create groups, or add users to a group. The syntax for entries in these files is defined in `man 5 sysusers.d`.
| |
|
| |
| By default, `systemd` provides configurations for required users like root, required groups such as wheel, and common system groups such as dialout, video, or users.
| |
|
| |
| The existence of `systemd-sysusers` ensures that a system can boot and be accessible, even if the /etc directory is not present - whether by design in a stateless system, or due to a system fault. Fedora 21 will still provide a default /etc/passwd and /etc/groups, and does not rely on `systemd-sysusers` exclusively to provide these system accounts.
