/* This service offers two Varlink services, both implementing io.systemd.UserDatabase:
|
|
*
|
|
* → io.systemd.NameServiceSwitch: this is a compatibility interface for glibc NSS: it response to
|
|
* name lookups by checking the classic NSS interfaces and responding that.
|
|
*
|
|
* → io.systemd.Multiplexer: this multiplexes lookup requests to all Varlink services that have a
|
|
* socket in /run/systemd/userdb/. It's supposed to simplify clients that don't want to implement
|
|
* the full iterative logic on their own.
