I decided to try autofs5 because it would bring us the ability to have direct maps for mounting all NFS filesystems. I set up an auto.direct that was really quite similar to our SunOS days. Since we don't really call much in /cse/local during system startup, I decided to move everything, even the mount of /cse/local to a direct map. I ran into a few problems.

When the system would boot up, /obj/cse would be mounted, /obj/home9, and /obj/home10, but nothing else. As it turns out, this is because of a bug in mountall. mountall mounts filesystems when the underlying block devices are ready, or when network interfaces come up, checking the filesystems first. When the system boots, and the network interface comes up, it calls /etc/init/mountall-net.conf which … text/html 2010-03-12T19:32:48+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.eecs.yorku.ca/dept/tdb/troubleshooting:start?rev=1268422368&do=diff Troubleshooting * mountall * autofs * gdm
