I expect this is the lowest version kernel you can be running executable programs on with this combination of gcc and glibc. > The /bin/date of Fedora 14 does run on Fedora 11 which is only Linux 2.6.30. > So there is no harm in this case, despite "not meeting the requirement."

They probably shouldn't be doing that. -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
