I was having a problem making the audio/teamspeak3-server port start fro =
the rc.d scripts on a -current box that I=E2=80=99ve just built. I =
eventually traced this down to it not starting in the correct directory.
Looking at the rc.d script I could see that it was attempting to chdir =
to the correct directory by setting the teamspeak_chdir variable. So it =
looked like this feature was misbehaving in some way.
To test this I put together an rc.d script for pwd that used =
${name}_chdir based on how the teamspeak rc.d script was setup. Running =
this on a 10.3 box showed that it was changing to the specified =
directory as expected, but on -current it was not.
I=E2=80=99ve taken a quick look at rc.subr on both boxes but I can=E2=80=99=
t immediately see what=E2=80=99s breaking this, and I can=E2=80=99t see =
anything in the setup or behaviour of the -current box that would point =
to it being something that I=E2=80=99ve broken somehow there.
I was wondering if anyone else could reproduce this?
Simple rc.d script for pwd

#!/bin/sh
# PROVIDE: pwd
# REQUIRE: LOGIN
# KEYWORD: shutdown
. /etc/rc.subr
name=3D"pwd"
rcvar=3Dpwd_enable
db_dir=3D/var/db/teamspeak
command=3D/bin/pwd
pwd_chdir=3D$db_dir
required_dirs=3D"$db_dir"
load_rc_config $name
: ${pwd_enable=3D"NO"}
run_rc_command "$1"

Running on 10.3 shows the expected result
