Inode numbers do indeed start from 1.  Craig Leres and I hacked
some of this code quite a bit after net.2 and before 4.4BSD---I
decided I could not stand the inconsitencies between the various
inode loops, and made them all be of the form:

	for (ino = 1; ino < maxino; ino++)

Note that this requires changing the code that sets maxino, which
currently says something like:

	maxino = sblock->fs_ipg * sblock->fs_ncg - 1;

with the `-1' factor existing to make `<=' correct.

This code is tricky and nasty; beware!
