autofs all setup, and it correctly mounts my shared directories.
However, right now, I have to manually run
sudo upstart autofs start after every boot, before the automounting actually works.
I think in installed
autofs manually through synaptic, though it has been a while. The computer in question is used as a lightweight server, and rarely gets restarted, so having to manually start a service isn't too big a deal, but my backups do not work until autofs is running, so I do worry.
