That HowTo is from me and reflects my current setup.cool.
Mounting filesystems on demand, is ecactly what autofs is made for.So on demand and if the connection is not used it will be closed and it will be remounted if needed. Which also means if the connection drops it will be remounted again. That sounds cool and I could use it for another thing I always wanted to get setup. I always wanted to have something similar for an SSH reachable share.
