| Ahhh! Indeed. A symlink from /home to /compat/linux/home made it work.

I thought that the emulation algorithm was to use, upon receiving a request
to open /foo, /compat/linux/foo if it existed, but otherwise to use /foo.
In this case, /compat/linux/home did not exist (right?), so I don't see why
it should have been using it.
So either:
a) I am confused, or
b) It is indeed a bug.
My money's on (a), but could anyhbody explain *how* I'm confused?
