If not, you cannot claim to support backward compatibility, even if you do on a subset of kernel/userland interface.

I will repeat myself here, but I ran what-was-to-become-Linux-v3.2 kernel on a 4 years old openwrt image and still had a functional system. Comparatively, I could not mix FreeBSD 7-STABLE userland and 8-STABLE kernel, The 8-STABLE kernel even changed the FS enough to make FreeBSD 7 unable to boot (even single user). Let me emphasize again that it is only my personal opinion :-) - ArnaudReceived on Tue Oct 11 2011 - 17:57:55 UTC
