Kernel legacy

Just to bring that back to discussion:

With lenny the provided glibc seems to be incompatible to kernel 2.4.
There are many systems out there still running with kernel 2.4 cause
stability. (My servers which needs to be stable all run Kernel 2.4.)

Is there any scenario what happens to such systems when lenny gets
stable?

Background: The glibc in lenny is compiled to be incompatible with
kernels lower than 2.6. I do not know if there are options to use newer
glibc with older kernels.

Regards
   Klaus

There is other software in lenny that isn't built to be compatible with
older kernels as well.  For example, slapd is built to use epoll, which
won't work with 2.4 kernels.  I suspect you will discover others that the
package maintainer may not even be aware of.

etch is already stable

The Linux 2.4 support ended with the Etch release. Even for Etch it is
only supported for upgrades.

Fix the kernel support in newer versions.

? lenny is still correct. etch runs fine with kernel 2.4 (and lower by
the way).

Yes, etch is but not lenny.

Since 2.4 is not supported by Debian and is barely supported by a few
kernel developers, it is hardly the stable option.  If you are aware of
specific unfixed bugs in Linux 2.6, I suggest you report them.

Maybe it works for you, but it is not supported.  This was made fairly
clear in the release notes:
http://www.debian.org/releases/stable/i386/release-notes/ch-upgrading.en.html#s-newkernel,
 
http://www.debian.org/releases/stable/i386/release-notes/ch-information.en.html#s-incompatible-2.4.

Ben.
