Comment 19 for bug 523484

To combine those last two comments, instead of using:

rm -rf /var/lib/ureadahead

I went for:

mv /var/lib/ureadahead /.ureadahead

which took an existing debugfs directory with it. That was the only content of the directory at the time. Other than that it all seems to be working fine, although I've not been aware of any performance improvement over what I was getting with the error and ending of ureadahead (but that's not the issue!).
