The delegation of the subordinate uids can be configured via the subid field in /etc/nsswitch.conf file.
Only one value can be set as the delegation source. Setting this field to files configures the delegation
of uids to /etc/subuid. Setting any other value treats the delegation as a plugin following with a name
of the form libsubid_$value.so. If the value or plugin is missing, then the subordinate uid delegation
falls back to files.

needs to provide a drop in replacement for libsubid via nsswitch.conf
