And in part because the compatibility issues are a pain. If a compiled
binary app uses fallocate(), then the app requires glibc >= 2.9.90.
fallocate() is not an exported symbol in glibc-2.9. The app won't run
on Fedora 10, or almost anything except Fedora 11, until it is re-compiled
to avoid calling fallocate().
The price of progress? :)
Perhaps the autoconf glue should have an explicit --enable-fallocate or
something; for F11 do we really care if the rpms in our binaries don't
run on debian stable or whatnot?
