systemd socket activation documentation improvements
Documentation for systemd socket activation should contain following:
- systemd-resolved should be
- kresd.socket should be
enabledand not the kresd.service (which is being activated, but this might be unclear to casual systemd users)
- for listening on public interfaces w/ socket activation is necessary to add FreeBind=true directive into [Socket] section
- maybe socket file can contain FreeBind=true by default as it is no harm on local interfaces
Hopefully this will make it easier for people who struggle to use systemd socket activated kresd.
