[Pkg-sysvinit-devel] Bug#482817: pidofproc and %PPID

[John van der Kamp]

Hi,

I've been trying to debug this myself too, and actually thought like in
bug #506995 that portmap was running twice, since it would be started from
/etc/rcS.d/S40networking (which kicks /etc/network/if-up.d/nfsmount.sh)
and also from /etc/rcS.d/S43portmap.
So I disabled the rcS.d portmap and nfs-common since the nfsmount.sh
script would start them, but then I still had the problem!

As far as I can tell now, /etc/init.d/portmap does:
   pid=$( pidofproc portmap )
The $() starts a new process, and pidof -o %PPID uses this as parent pid.
But the /etc/init.d/portmap script is also running, and recognized, making
the pidof program return a of the init.d script.

I've fix it like this, but you're welcome to make your own conclusions and
fixes :)

Since I don't know of a way to capture the output in a variable without
using $() or ``, I let it check the return value of pidofproc.
