[ANNOUNCE] mini_fo-0.6.0 overlay file system

[Markus Klotzbuecher]

mini_fo is a virtual kernel filesystem that can make read-only file
systems writable. This is done by redirecting modifying operations to
a writeable location called "storage directory", and leaving the
original data in the "base directory" untouched. When reading, the
file system merges the modifed and original data so that only the
newest versions will appear. This occurs transparently to the user,
who can access the data like on any other read-write file system.

mini_fo was originally developed for use in embedded systems, and
therefore is lightweight in terms of module size (~50K), memory usage
and storage usage. Nevertheless it has proved usefull for other
projects such as live cds or for sandboxing and testing.

For more information and download of the sources visit the project
page:

ChangeLog for mini_fo-0-6-0:
   - support for 2.4 and 2.6 kernels.
   - mini_fo now implements all file system operations.
   - many bugfixes and code cleanup.

Hi Markus.

This sounds interesting.

Could you post the patches in the list so that we can discuss
them properly?

The module is currently built outside of the kernel sources, how would
you like me to post it?

Yes, so we can discuss them...

It's a very useful functionality that's I'd like to be present
in the vanilla kernel if possible.
