The more I look at this, the more I prefer your original approach that
prefixed the relative pathname with the fstype.  Yes, I do realize
that you sort of work around that by including the fstype as a new
field in the PATH records, but we're still stuck with those odd
relative/un-rooted name fields.

Further, I don't recall ever hearing a good reason why the original
approach wasn't acceptable to Steve's userspace.  I know he did make
some very last minute hand-wavy comments, but none of those made any
sense to me; I don't understand why Steve's audit record parser is
even looking in the pathname string.

I'm going to park these patches in limbo for the time being.
