You're telling me..  Yes I can compile an 2.6.5 host, an 2.6.5
UML, and an 2.6.6-rc1/2/3 HOST, but not an 2.6.6-rc1/2/3 guest.

Ok.  If it where including kernelspace headers I don't think
this would be a problem.

As I understand it SID installs as it's 'de facto' headers not
2.6, but 2.5.999-test7. See: http://packages.debian.org/unstable/devel/linux-kernel-headers



And it would seem that this area (in kernel headers) has recently
changed (when compared to 2.5) or up to this point UML builds
have been going against kernel provided headers instead of the
2.5 headers debian's shipping.

I'll try it, but I had really hoped not to mess with those headers
as it's my understanding that important pieces of code (ie glibc,
etc) are compiled against those headers.



I'll write back to the list whatever I find out.



Thanks,
