OK, then the daemon should remain running as long as there is at least one entry in the master map. If the daemon receives a HUP signal then any mount handling threads that terminate will send SIGTERM to the signal catching thread. If the master map becomes empty during this SIGTERM check autofs will exit. That is what the daemon exit condition is and we do need such a condition to be able to exit at all. If something else is happening in your case then we need to work out what's going on. However, there are a couple of patches against 5.0.4 in this area of the code, but I'm not sure they make the above behaviour different.

As it should if there are no master map entries remaining. I've been here before and I think trying to change the exit condition will be quite hard. > > I've got a 2.6.27.9 kernel, patched with > > autofs4-2.6.27-dev-ioctl-20081029.patch and > autofs4-2.6.27-v5-update-20081027.patch > > Stef Bon > _______________________________________________ autofs mailing list autofs@linux.kernel.org http://linux.kernel.org/mailman/listinfo/autofs
