Subject: [PATCH] Add directives for numerically specifying GIDs/UIDs
The already present directives (FileOwner, FileGroup, DirOwner,
DirGroup) translate names to numerical IDs, which depends on the user
information being available during rsyslog's startup. This can fail if
the information is obtained over a network or from a service such as
SSSD. The new directives provide a way to specify the numerical IDs
directly and bypass the lookup.
