I agree with you and Charles. Thank you.
Should the rc script care at all about the lock file, or should it be
totally left to the installer/coder of the script? As it is now, the rc
script cares ONLY if you follow a certain convention. Again, in my
ignorance, is the name of the lockfile documented anywhere? I did not
find it in the tldp.org pages.
Thanks.
