This may or may not be of relevance...

For a while during the 2.2-x-SNAP period I tried to run with a readonly
/usr, and change it to read/write with mount -u when I needed to update
it. I often ended up with a corrupted file system, and sometimes with
a panic. Fortunately, fsck was able to fix the problems.

(I quit trying to use a readonly /usr because of these problems.)
