Since /dev contains a special filesystem which cannot
be used for "simple" files and directories, I would say
that the IDS needs some knowledge about it and generic
file-checking rules don't apply there.

This sounds like a false alert, something must have changed
from 8 to 9 and/or the ossec port (and/or ossec signatures).

Disclaimer: I am not an ossec user!

Would be interested in the answers too.
