Or perhaps the order the export list is returned is no longer a problem. The attempt to remount on umount fail has always been a contentious in my opinion, however I`ve yet to see a situation that hasn't been caused by something else that needs to be fixed. I thought I asked for versions? Can we have`em. If neccessary looking at the code will tell if you have what's needed to avoid this. Send me a copy of parse_sun.c from the source you are using and I'll check.
