On RHEL4, syscall auditing and file system auditing cannot be mixed on the 
same line. Watches can only take -p & -k parameters.

Are you on x86_64? If so, you should use umount2. I believe this is documented 
in capp.rules.

x86_64? If so use the syscall, shutdown. (offhand, I don't know why you would 
need to audit shutdown.)

stime is valid on i386. maybe settimeofday?
