fsck reports that all is well.

Pretty much, yeah.  And loader's "lsdev" shows the devices, slices, and
partitions just fine.  But loaders's "ls" doesn't find /.

Toomas has recieved a "dd" image for the first 5 MB of the file system,
and has reproduced the issue in hist test environment, so I'm hoping he
will be able to figure out a bit more.  (It's at
https://www.catwhisker.org/~david/FreeBSD/head/loader/ada0s4a, in case
anyone else wants a peek.)

Right: no GELI for any file systems on this machine (only for swap).

Thanks!
