I agree that it would be tricky to handle within the startup
scripts.

But it doesn't seem like it should be hard to handle within
fsck itself.

The first time fsck gets invoked by rcNG, it is given the -F
flag which, according to fsck(8) does a foreground check on
"all the file systems that cannot do background checking."

I think that "system rebooted during a bg fsck" could qualify
that FS as being unable to do background checking.  What's
needed is some way for fsck to mark a filesystem as having
a bgfsck in progress.  Then fsck -F can check for that marker.
