Re: Patch wheezy's glibc to run on ancient kernel (2.6.16)?

Sure, for debian it is fine - however for me, being limited to that
old kernel, it is a showstopper.
Granted, the use-case is rather obscure ;)

Thanks for the hint about debian/debhelper.in/libc.preinst, I would
have missed it for sure.

Package rebuild went without any issues on a chroot-wheezy on my
raspberry, and the patched wheezy works perfectly on my Nokia-770 with
Linux-2.6.16, and is currently compiling stuff directly on the target.
To my surprise the linker didn't complain at all, even though all
libraries and binaries contain 2.6.26 as minimum kernel version.

To me this shows one of the benefits of the loose coupling the
packages within a linux distribution - running Windows-7 userland on a
WinXP kernel wouldn't be that easy I guess ;)

Best regards and thanks a lot for your help, Clemens
