is autofs a filesystem

one of my collegue says that autofs and nfs are both network based filesystems.
nfs i have worked upon but not used autofs anytime.

as far as my understanding goes, autofs is a tool/package/daemon which allows us to specify various filesystems. and these filesystems are mounted and unmounted automatically when they are used/left aside..

so is it a filesystem per se?

autofs is a kernel-based automounter for Linux. It performs a job similar to amd but relies on a small stub of kernel code instead of pretending to be an NFS server. The result is simpler code, better reliability, and much faster operation in the common case (everything already mounted).

Bottom line, like they said, AutoFS is not a filesystem. From Wikipedia: "Formally, a file system is a set of abstract data types that are implemented for the storage, hierarchical organization, manipulation, navigation, access, and retrieval of data." Autofs is a deamon that mounts file systems. Using fdisk, you can see a list of file systems, I believe the command is "n" from the menu. You will find EXT2 and 3, NTFS, NFS, ReiserFS, and a bunch of others. AutoFS will be absent.

>>Using fdisk, you can see a list of file systems,

Hi kiranghag,

I think better argument is :

If autofs is filesystem why it is in folder where daemons are?
