A checksum doesn't tell me that someone hadn't temporarily : replaced the file and has now put the original back. Ummm, you still can't tell that for a competant attacker. A good attacker can set the system time, frob the file, set it back let time pass and then do the same thing to get the original back. You'd never know. It is a bug in the FreeBSD VM system where a page gets marked as dirty, but the underlying pages are hardware protected against write, so the same contents are written out. Warner
