Reserved UIDs and GIDs
======================

Users and groups are created once needed at package installation. It's perfectly
safe to reuse the same UID/GID for different packages (example www, mail).

Users and group that are private and only used by the software must be prepended
by an underscore. Only groups that users can join can start without one.

The following UID/GID are defined:

| uid                 | gid                 | package(s)           |
