... i'm looking at the tools we use to build install machinery as part
of another project. And to come back to the 4Mbyte i386: there still
a few  options:

* We can do /tmp as a ramdisk devices -- newfs them and use the old
  script-installer symlink hackery. Possibly even the same thing with

* You dont *have* to run sysinst out of a ramdisk. we can do a
  sysinst-based install from disk, running either from the start of swap
  (as 4.3bsd did), or from a root filesystem newfs'ed as full-sized by
  the ramdisk, but containing the same stuff as an install ramdisk
  (as 1.3.3 does on pmaxes).

Once theres' a swap partition on the disk the problem is, effectively,
solved. And by adding enough floppy pre-install stages (like the workaround
for pcmcia), we can get there, and then run sysinst. Cant we?
