-Subject: [PATCH] firewall3: fix locking issue
-
-By calling the command 'fw3 reload' several times at the same time, I
-noticed that the locking was not working properly. It happened from time
-to time that some firewall rules were present twice in the system!
-
-By removing the 'unlink' systemcall, this error no longer occurred on my
-systems.
-
-Since fw3 does not run as a service, it makes no sense to delete this
-lock file every time a filehandler is no longer open on this lock file,
-because fw3 binary is not running.
-
-If fw3 does run as a service then we can remove this lock file on
-service stop. But this is not the case for fw3.
