Owl and 2.6 kernel

Hi together,

I had to exchange several machines with newer hardware and now I have to
use a newer kernel (2.6.25) because of the unsupported ICH9 chipset in
2.4.35.

Are there any roadmaps/timetables to switch Owl to an 2.6 Kernel, or do
I have to use an unpatched kernel for my new hardware?

Which packages are kernel-dependent and should be rebuild under the new
kernel?

Any experiences?

Greetings
Bernhard

Try building 2.6.24.5 with grsecurity.org's patches (most of them
are not really needed, but some are really good).

None I'm aware of.

I use Owl with 2.6 kernels for over 3 years and have no problem
with that.

We wanted to do it before the next release, but right now it seems more
likely that the next release will be the last one to use a 2.4 kernel -
that is, that we'd switch to 2.6 after the next release.  We are also
very likely to integrate OpenVZ.

Yes, if your hardware is unsupported by 2.4 kernels, you'll have to use
a 2.6 kernel without our patches.  We're often using the OpenVZ kernels
from OpenVZ's "RHEL5" branch.  They work fine with the Owl userland,
which we use both on the host system and inside containers (also known
as VEs or VPSes).

The short answer is: none.

In fact, it is more correct to have your packages built against the same
kernel headers that glibc was built against.  So if you don't rebuild
glibc (and there should be no need to do that), it is more correct to
not rebuild any other packages against 2.6 kernel headers as well.

An interesting link and possibly a candidate package for Owl

Hello,

The following technology looks promising and we might want to consider
it for an inclusion into Owl.  Is anybody interested in such a package?

Ksplice - allows applying patches to the running kernel.  More info at:
