This could be a good idea since it would fix a big outstanding issue: The
inability of MacOS VM to lock contiguously enough space for the kernel
and ramdisk in lots of cases (the -622 error most people with virtual
memory ON are experiencing). If the booter was itself a nini-kernel that
takes care of further loading of the real kernel and ramdisk, this issue
would probably disappear.
Another thing that Paul and I are trying to define and implement: A way
to completely boot from a disk image on the HFS volume (and eventually
use this image as the read/write root volume). This would allow
installations of Linux on top of macos without reformatting &
repartitioning the hard disk.
