[Unionfs] BUGS in unionfs with NFSroot (2.6.23-rc5 + 2.1.3)

[Erez Zadok]

Jan-Marek,

The short answer is that yes, unionfs can be made to work w/ nfsv4.  I've
had unreleased patches for some time, but they're not as clean as I'd have
liked them to be.  I was hoping to wait until the patches to split nameidata
into a lookup-intent structure made it into the kernel, but I guess we can't
wait for that now.

As for the other bugs w/ nfsv3, please submit a bugzilla report on this so
it'll be easier for us to track the bug.  Next, I'd like to reproduce your
setup (preferably in vmware).  Do you have a livecd image I could download?
A tarball w/ your configured kernel sources, however modified?  That'll help
a lot.

Thanks,
Erez.
