Caveats
There are a few "side effects" that come with files that are mounted using automounter, these may differ depending on how the service was configured.
- Access time of automounted directories is initially set to the time automounter was used to mount them, however after the directories are accessed, this statistic changes.
- On some systems, directories are not visible until the first time they are used. This means commands such as ls will fail.
- If mounted directories are not used for a period of time, directories are unmounted.
- When automounter mounts directories, they are said to be owned by root until someone uses them, at that time the correct owner of the directory shows up.
