Hi Erez,

You should recall that I put the latest version of Unionfs (Unionfs
2.14 I believe) into the to-be-released  Gutsy Gibbon kernel back in
September this year.   Subsequently I spent two weeks tracking down
issues, putting in bug fixes, and generally getting Unionfs 2.1.x to
work with the Ubuntu liveCD.

Since late September I have been off work due to an accident.  During
that time another Canonical team member reverted Unionfs back to 1.4.
I don't know why this was done, but I can only assume additional
issues were found with the liveCD, and a reversion back to a known
working Unionfs 1.4 was felt to be the best option.

Moving forward I believe Hardy Heron will and should support Unionfs
2.x.  Obviously, however, this can only be done once Unionfs 2.x works
correctly with the liveCD.  If you're willing to help track down any
issues we experience then that will be very helpful.
