FYI, here's the patch that fixes the "df" problem that Christian
reported.
If I recall correctly, it took me about a day to figure out that the
problem wasn't in df, wasn't in the 2.11 BSD C library, but was in the p11
emulator. The fact that the same disk image booted by Bob Supnik's SIMH
PDP/11 emulator produced correct "df" results was the big clue. Here's
the
fix for p11 (version 2.7).
