Not, it's much worse than that: UFS will not re-read cached data for
the read-only mount so the read-only mount will continue to use data
which is stale; e.g., once a file is opened and as long as its inode
is in use (file open) or cached, you will never see a change to the file.
You will never notice changes to data unless you no longer cache it.
Panics and random data reads are guaranteed.
