SubjectRe: safe file systems
The filesystem you're describing is called a "journaled" filesystem...
The system "journals" all writes, so that if an operation doesn't complete
(ie. in a crash), it can be "rolled back" (reversed) safely.

I believe that there is a group vaguely working on one, but my memory
falters...
