The file system watches in 1.1.5 are the kind that the RHEL4 kernel is 
expecting. We had trouble merging the patches into the kernel.org kernel and 
had to spend a long time rewriting the subsystem.

Right, so you just move the rule to the exit filter.

The file system watches are scheduled to land in the 2.6.18 kernel. We have a 
test kernel that you can test with in the mean time:

This mail list is a good place to ask. We have not done much in terms of 
tutorials or HOWTOs because half the audit system has been missing from 
common kernels. The 1.2.x series audit packages is reworked to fit the file 
system audit code that goes with the 2.6.18 kernel. I will push that into 
Fedora Core 5 when 2.6.18 starts into the rc phase. So, if you want to 
experiment, install a lspp kernel and build a 1.2.x audit package for fc5. 
You should be set.
