The second part about POSIX file capabilities was realized shortly afterwards while thinking of possible other similar cases, and has been fixed too now: http://rpm.org/gitweb?p=rpm.git;a=commitdiff;h=4d172a194addc49851e558ea390d3045894e3230 To my knowledge no distro actually uses the file capability support in RPM though. - Panu -
