Re: [Wrapper-user] Wrapper doesn't call stop() during machine restart on Fedora

[Leif M. <le...@ta...>]

Donatas,
    Good work tracking that down.   Looking at Debian at least. the 
/var/lock/ directory
exists, but not the /var/lock/subsys/ directory.   One thing that I 
could do is to look for
the /var/lock/subsys/ directory and create that lock file if it 
exists.   It might make more
sense to do it within the wrapper process however, that way if the 
wrapper process
dies, the lock file will get deleted like the pid file does.
    Opinions on this from anyone else welcome as well.  Not really sure 
what is best
here.  Though I would like the scripts to work out of the box as much as 
possible.
    How do other application scripts function on Fedora?  If they are 
designed to be
run on linux systems as well, I could take a look at them for clues.

Cheers,
Leif
