Google Groups revealed the following:
http://lists.freebsd.org/pipermail/freebsd-questions/2003-June/008898.html

[root at optimator:~] $ dumpfs /usr | grep clean
cgrotor 512     fmod    0       ronly   0       clean   0
[root at optimator:~] $

Using dumpfs(8) for this purpose is a little like using a jackhammer to 
drive a nail into drywall; it Gets The Job Done but there sure is a lot 
of noise and heavy lifting... :)
