I just installed and configured autofs on Ubuntu 12.10, so that the /home Folder is automatically mounted from a NFS server. Most tutorials suggest to just run
ls /home and then those directories should be mounted and visible in the output. Well as it turns out, they are not. I spend at least half an hour trying to figure out what is wrong. Once I tried to log in as any user, using my ssh key, it just worked and only this users directory got mounted.
So screw the test with ls!
