The reason I saw was so code didn't have to check for certain features at run time. The would be to make things easier for the programmers. 2.6.18 corresponds to RHEL 5 and is a compromise for backward compatibility and convenience. 2.6.18 was September 2006. Using 2.6.18 appears to potentially affect binaries built against kernels older than that and run on a LFS-6.5 or later system. I don't see where that would be an issue. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
