--------
This looks very similar to ports/62477.
If mpd started after ppp with pppoe setup then mpd works fine.
Executing
/sbin/ifconfig fxp0 up
/usr/sbin/ngctl mkpeer fxp0: pppoe orphans ethernet
before mpd also make mpd happy.
It looks like
1) mpd doesn't put interface into UP state and
2) mpd fails to create netgraph hook
>How-To-Repeat:
Reboot a system
Run mpd with pppoe setup
>Fix:
Workaround:
Execute
/sbin/ifconfig fxp0 up
/usr/sbin/ngctl mkpeer fxp0: pppoe orphans ethernet
before running mpd.
The following startup script will help starting mpd in such a situations:
---------
#!/bin/sh
# PROVIDE: mpd
# REQUIRE: netif isdnd
# KEYWORD: FreeBSD nojail shutdown
. /etc/rc.subr
name="mpd"
rcvar=`set_rcvar`
mpd_start_precmd()
{
/sbin/ifconfig fxp0 up
/usr/sbin/ngctl mkpeer fxp0: pppoe orphans ethernet || true
}
mpd_stop_postcmd()
{
/usr/sbin/ngctl rmhook fxp0: orphans
}
load_rc_config $name
start_precmd="mpd_start_precmd"
stop_postcmd="mpd_stop_postcmd"
command=${mpd_program:-"/usr/local/sbin/mpd"}
pidfile=${mpd_pidfile:-"/var/run/mpd.pid"}
flags=${mpd_flags:-"-b -p ${pidfile} ${mpd_profile}"}
run_rc_command "$1"
---------
It would be nice to switch mpd to rcNG startup script. This one can be used after this issues have been resolved and workarounds (mpd_start_precmd/mpd_stop_precmd) removed.
