[Debian] [vorlon@debian.org: Bug#400675: kernel-patch-openvz: patch still not applying cleanly]

[Ola Lundqvist]

Hi

New versions of the kernel will be made as it has serious bugs. I'll check
if it applies during the weekend.

Regards,

// Ola

You've probably seen by now that -9 has been uploaded.  There will
definitely be a -10 as well for etch, there are still outstanding RC bugs
that need fixing; but -9 needs to be the final ABI and therefore shouldn't
(I hope) be including any more large upstream merges.

Well, the lack of surety is what has me concerned.

Is the security team aware that this is the case?

Yes, which means any problems with those patches are detected at build time
for the linux-2.6 package -- clearly not the case for openvz right now.

This bug was re-reported because the current version of the openvz patch
package doesn't apply against the /previous/ version of the linux-2.6
package.  The common case here has been that the openvz patch hasn't been
updated to apply to the current version of the linux-2.6 package.
