Obsolete files detector

Is there some program for automated checking entire QNX 6.3 fileystem
for obsolete system files? I mean files (drivers, commands etc) which
in given moment of time should be newer if all relevant patches had
been installed.

I have recently had issues with obsolete serial driver residing in
apparently updated systems. I fear that there can be more such
potential problems in my systems and I like to fix it without complete
reinstall if possible.
