some days ago I searched for unionfs and lookalikes to set up a diskless boot and wondered.
there is more than just unionfs:
unionfs-FUSE is based on unionfs with some interesting features
aufs is a new implementation of uionfs. knoppix just switched from unionfs to this one.

none is in kernel but FUSE annd unionfs-FUSE runs in userspace.
none has good documentation .-(
special tricks like root mounting are not documented.

Hi dambacher,

we are just trying to use funionfs (also fuse based) as diskless setup. In principle it already works, but I found one critical bug, see here

http://www.fsl.cs.sunysb.edu/pipermail/unionfs/2007-Janua...

I looked into the sources of unionfs-fuse and I think it will have the very same access() problem.

All I need is a good idea how to fix it. Since everything is done in userspace, the source code is rather simple.

If you need some help to setup your diskless setup, just contact me.

Cheers,
Bernd
