Details

Description: /etc/rc.d/i8kmon stop will not stop the daemon. This is because the PID numer is determined by pidof inside the script, whereas the ik8kmon is run in tclsh session so pidof fails and returns nothing.

Steps to reproduce:
Install the i8kmon package, start and stop the daemon.

well, the entire setup is really bad
1) rc.d-style schemes requires the daemon to self-background
2) i8kmon in addition forks into a tclsh shell

Solutions:
- use a pid file. This doesnt work b/c i8kmon forks
- use init with a non-forking i8kmon
#!/bin/sh
while true; do
i8kmon -d
done
- alternatively, use daemontools. Unfortunately this adds an extra dependency, but it might be worth it
- Use pgrep. Very ambiguous and possibly unsafe, but only feasible solution. Change /etc/rc.d/i8kmon to
#PID=`pidof -o %PPID /usr/bin/i8kmon`
PID=$(pgrep -G root -ofx "tclsh /usr/bin/i8kmon -- -d")
- the above entire process can be simply automated by start-stop-daemon. Arch doesnt have start-stop-daemon

Problem (temporarily) solved

This software is no longer maintained upstream and I'm considering it for a move to community or unsupported.

@Thayer: this task can be closed? The pkg is still on [extra] repo.

hm, I use i8kmon on my laptop, I don't think I've noticed some problems with it, though I agree that it looks crappy and its use of tcl is crazy,
I should take a look on it during weekend. Anyway I agree that it should be better moved to AUR.

I'm on it (hurray for the Bug Squashing Day!).
Found an elegant solution: fuser -k /proc/i8k :-)

I wanna kill the dev who wrote 'fuser' program!
# fuser /proc/i8k
/proc/i8k: 2081
The '/proc/i8k:' part is from stderr, the PID is from stdout!
I tried to cut/sed/grep the PID and could not realize why nothing works :P

Fixed. Also changed to -any package (which it is).
@Thayer: there is an updated version at http://packages.debian.org/sid/i8kutils.
If you don't want to maintain the package anymore - I can take it (either in extra or community).
