SubjectRe: [ANNOUNCE] submount: another removeable media handler
Date

> how is it different from what automounter does?

Autofs works by creating a special filesystem above the vfs layer, and passing
requests and data back and forth. Submount actually does much less than
this- it puts a special filesystem underneath the real one, and the only
things it returns to the VFS layer are error messages. It handles no IO
operations whatsoever.

Peter Anvin has called using the automounter for removeable media "abuse."
Submount is designed for it.
