The initial emphasis wasn't so much to clean up the bootblocks, but to get
around the fact that MAXPARTITIONS is hard-coded in the library, and since
it varies from port to port on m68k, they can't share libc.

Wouldn't offloading routines from libc to another lib be removing routines
from libc, which usually entails bumping the major #?

Take care,
