LogControl1 D-Bus API which allows clients to change log level +
target of the service during runtime.
+ * Various command line parameters and configuration file settings that
+ configure key or certificate files now optionally take paths to
+ AF_UNIX sockets in the file system. If configured that way a stream
+ connection is made to the socket and the required data read from
+ it. This is a simple and natural extension to the existing regular
+ file logic, and permits other software to provide keys or
+ certificates via simple IPC services, for example when unencrypted
+ storage on disk is not desired. Specifically, systemd-networkd's
+ Wireguard and MACSEC key file settings as well as
+ systemd-journal-gatewayd's and systemd-journal-remote's PEM
+ key/certificate parameters support this now.
