This is normal. Fortify source should be enabled in all builds unless it
is explicitly turned off. However, if the examined binary doesn't use
any of the functions that would benefit from fortify source, then the
reporting tool can't determine if it was compiled with fortify source or
As for PIE and BIND_NOW, these are disabled by default and opt-in for
packages that want them. The reason PIE is like this is because it can
introduce a performance penalty on some architectures like i386. I don't
recall why BIND_NOW is off by default-- presumably for the same reason
(maybe someone else on the list can comment). See our wiki for more
If there are packages that you feel would benefit from enabling PIE,
then I suggest filing a bug against the package with `ubuntu-bug <pkg>`.
