I get the argument Dave is making. But the reality of forensics is
that many of our tools are not reliable in all cases. We do a lot
of cross-validation for crucial results.
Having multiple tools helps. Right now, we basically have nothing
for XFS. So adding this option to xfs_db makes things better.
We work with underplayed file systems constantly, and it’s
less of a worry than you might think. Try my patched version of
xfs_db on a live file system of your choice. See if you can make
it blow up. When it doesn’t, please consider folding in my
patch.
And the source code to your new and improved xfs_db can be found
where? I'm interested to know how you've solved the problem of
detecting stale metadata from userspace on a live filesystem...
I believe he's referring to the patch he just sent, Dave.
