I would comment out the SYSFS lines and see if that fixes anything. I
would also remove the executable bit {chmod -x filename).
It seems they have put both SYSFS (used in RHEL5, so really old) and
ATTRS (new name RHEL6(say f12) and newer), but both point to the same
place, so as long as the bad one is not causing it to abort the entire
rule execution it should still work.
And read brothers documentation carefully, I think I found extra
instructions in one of their pages (I just remember the scanner being
tricky to setup for me).
