I have built one kernel flavour (vserver) for each architecture (i386,
amd64) and Ubuntu release (hardy, intrepid, jaunty).
All of them are based on the Ubuntu mainline kernels. I have just
applied an adapted Linux-VServer patch and made minor modifications to
the packaging in debian/ so that only the vserver flavour gets build.

Setting up a git tree sounds good although I never worked with git up
till today.

That would be adapting the vserver kernel to every kernel SRU and
keeping up with the development version?

Would be fine.

Hm. Supplying up-to-date kernels for multiple Ubuntu releases might take
some time. Probably it would be better to have a Vserver team of at
least two people.

Thanks a lot for your feedback.
