If you don't mind, I'd like a proper reference for this; looking at the Linux kernel documentation as you suggest tells me that the kernelspace to userspace ABI is supposed to be 100% stable, such that I can take all the binaries (including shared libraries) from an i386 Linux 2.0 system, and run them in a chroot on my x86-64 Linux 2.6.35 system.
Maybe it's "supposed" to be, but even with more recent stuff (like, say, binary GHC releases --- which use glibc shared even if Haskell libs aren't) I quite often see programs fail to run because the kernel changed something and the kernel/userspace interface changed as a result. A written policy is worthless if it isn't followed.
Well, I have no need to recompile glibc and packages that depend upon it every time I update my kernel... So maybe glibc changes, but not the kernel AFAICT. -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
