Adjust a couple of things to use less temporary space:
...
+ build the passwd file before copying in ramdiskbin
+ don't copy MAKEDEV, run it, then delete it - run it in-place from
${.CURDIR}/...../etc.i386/MAKEDEV
Also, use LINK instead of SYMLINK for files under /usr - it's not a
separate filesystem.
Fixes PR misc/11473 and port-i386/11504 (until something else grows
again).

Rearrange bootfloppies. The idea is that "rescue" tools go on the
...
floppies as long as they fit, but they are the first to be sacrificed
if space is short, and get moved to a seperate rescue floppy.
This means that the default fdset and the 2.88M image have them,
but others (the "small" and "tiny" floppies) do not.
Sysinst is also back on the "tiny" image, and tested to be working
within 4M.

Fix the previous in another way:
...
o Wave goodbye to INSTALL_SMALL-based boot image (it was originally
built for 5.25" media, but isn't anymore).
o Make a separate ramdisk image for the INSTALL_TINY image,
using the old script-based installer (not fixed/checked at the moment).
However, at least tweak the profile scripts to start it instead of sysinst.
Also remove ping6 and rtsol from ramdisk compared to original; the
INSTALL_TINY image doesn't have INET6.
o Add dump/restore back into both ramdisk images.
o Add scsictl and chio to the normal ramdisk image (INSTALL-based fdset)
o With dump/restore reinstated, remove the rescue-* and ramdisk-rescue
directories.
So, we're now back to having the recovery tools on the same image as
the boot media images.

The images built are
rescue1.fs
rescue2.fs Based on the full INSTALL kernel, on two floppies
rescue-sm.fs Based on INSTALL_SMALL

People who want to be able to install files which have been translated

Modify all calls to newfs in ramdisk/miniroot creation to include

the needed endianism of the architecture. One step towards cross-building
releases.
Not touched are newfs calls in install scripts as they run on the desired
machine and thus default correctly.

1) Remove all vestiges of tar from src/distrib. Use pax and appropriate
...
commandlines for all tar operations. (work supplied by Matt Green)
2) Update arch/*/md.c to deal with new sysinst/run.c. Special case
anything that needs to do a redirect or a pipe.
3) #if 0 some unused code in target.c. This code will need to be updated,
or special cased with do_system.
Big thank you to Matt for all his work on this.
