Using Jessy with an older linux kernel

[Freek Dijkstra <debian_public@macfreek.nl>]

Hi,

Is it possible to run Jessy software and packages with an older (3.2 or
even 2.6) Linux kernel?

The VPS that my hosting provider offers, uses OpenVZ (or more likely,
it's commercial counterpart, Odin Virtuozzo). OpenVZ provides operating
system-level virtualization (unlike paravirtualization as offered by Xen
or KVM). This means the kernel can't be changed from the guest OS, only
from the hypervisor. So I'm stuck with an older kernel.

I've been successful in upgrading from Wheezy (7) with a Linux 3.2
kernel to Jessy (8) on a test-VPS, and everything seems to work fine.

My production server is still running Squeeze (6.10 with LTS), with a
Linux 2.6.32-042stab092.3 kernel.

While I expect an upgrade will work fine here too, I do like to get some
understanding of the risks.

Which packages would have dependencies on a kernel, in particular
dependencies on a more recent kernel?

Thanks for any insight you can provide!
