On Sun, Jan 08, 2006 at 01:09:15AM -0600 I heard the voice of
Matthew D. Fuller, and lo! it spake thus:

I just updated to today's (well, yesterday's) -CURRENT, and still saw
this.  Nobody responded to the original mail, and nobody else has said
anything about it, so I'd assumed it was just a passing thing in the
old -CURRENT, but it still happened in the new, so I moved to assuming
it was something screwy with my system.

And so it was.  Strangely, if I unmounted the filesystems that
wouldn't mount -u, delete the dir they're mounted over, and recreated
it, they picked back up and worked just peachy.  Those dirs, as a
rule, hadn't been touched since 1999 when I installed this system.
And (for instance) the /usr dir that /usr is mounted on hasn't been
touched since then either, but is still working just fine without
intervention.

I still don't know WHY that started happening, but there's how to fix
it if anybody else hits it.
