Inherited Filesystem for Linux

Inherited Filesystem for Linux

[Terry Barnaby]

Hi,

Is there or is anyone working on an Inherited file sustem for Linux
(2.6.x kernels) ?
I have seen very old postings on this issue but nothing recent.

If not is there any good documentation on how to implement a kernel
filesystem ?

My application is a number of diskless nodes that I would like to share
a basic file system, but allowing each node to have differing files
for configuration differences etc. So any writes made to the
Inherited file system would result in a file copy from the underlying file
system and a write to the newly copied file.

Cheers

Terry

maybe this provides a good starting point:

http://vserver.13thfloor.at/TBVFS/index.php?page=Linux+Implementations

Ovlfs is back, e.g. it's used by the SLAX LiveCD, kernel 2.4.25.

	http://ovlfs.sourceforge.net/
	http://slax.linux-live.org/changelog.php

I don't know how stable it is.

Hi Herbert,

Thanks for setting up this Wiki for the template file system
I have added a few bits if that is Ok ?
Some words I notice missing from the Keywords and on the main page
is "Inherited" and "IFS". This is sometimes used for this type of file system.

Cheers

Terry
