After installing openrc and openrc-services, one is booted to a command line
 with only minimum of services enabled.

Some common services that could be enabled:

# rc-update add dbus default
# rc-update add sysklogd default
# rc-update add dcron default
# rc-update add alsasound boot
# rc-update add consolekit default
# rc-update add NetworkManager default
# rc-update add dmeventd default  # if using lvm
# rc-update add lvmetad default   # lvm

Enabled services for current runlevel can be queried with:
$ rc-status

Enabled services across all runlevels can be queried with:
$ rc-update

Note: Services are installed to /etc/openrc/init.d
