- use libhack to avoid dragging in YP and DB (saves about 108K of libc
we have no need for).
- use more of the -DSMALL utils from distrib/utils/x_* (saves about 76K)
(except x_gzip, which is actually bigger).
People who want to be able to install files which have been translated
into EBCDIC, or install over XNS, can probably figure out other ways
to get this done.
This means that a boot image again fits on a single 1.44M floppy, with
about 50k to spare.
Move to use init_s to make room for sysinst
(Note: sysinst is not automatically run, it still uses the old install
process. One can choose "shell" and then run sysinst to use it.)
