I am confused recently about sd-dbus && dbus-daemon.
lenart says from v221 release of systemd use sd-dbus API
I read some blogs and get a result , but do not know is it correct?
there are 3 kinds of dbus libarys
Is it correct ?
we konw dbus-daemon is based on libdbus .
But we know systemd have a dbus-daemon also ? why lenart says systemd is based on sd-dbus but not libdbus?
lenart says after v221 release of systemd use sd-dbus API, But I see before v221 there are sd-dbus in source code also ,that's why ?
