I don't believe this is likely to happen, fwiw; we can certainly have the
discussion, but supporting two-year-old kernels for LTS upgrade purposes
already requires ongoing work, and I don't believe we're ever going to be
able to support running the Ubuntu userspace on an arbitrary non-Ubuntu
kernel except on a best-effort basis (like in this case).

When declining the release notes task I was thinking in terms of chroots
which can easily be recovered after the fact. Xen is obviously a different
matter; given that this also affects running on Xen, I agree we should
document this in the release notes.

Under the circumstances, perhaps it's better to simply use the release notes
to warn users off of upgrading to 10.04 until these issues are fixed, and
focus on getting these SRUs done?
