Yay!

Your proposal is pretty high-level and it sounds good to me so far. You 
might also want to search archives as this was discussed in the past 
and, I think, Christopher Santero even sent some patches, but I don't 
know what happened to that.

One note about fsck: in addition to manually requesting fsck, it would 
be nice to do so automatically prior to mount, perhaps by default for 
those filesystems that support "dirty bit", and by letting users force 
it (say) via GConf tunable for those filesystems that don't.
