pre3:
	- ybin: Correct a verbosity message.
	- Add non-fatal warning when bootstrap partition has wrong type (pmac only).
	- Minor code rearrangment.
	
pre2:
	- Fix netboot when using the `n' key.
	- Make configuration file open error consistent with other file open errors.

pre1:
	- Add SGI XFS filesystem support.
	- Rewrite OpenFirmware device path parsing code.  This fixes
	  many bugs and inconsistencies in yaboot's file loading.
	- Fix OpenFirmware filesystem support to automatically convert
	  path separator from / to \.  CDROM authors no longer need to use
	  hacks like image=\\install\\powermac\\vmlinux.
	- Fix kernel loading on some systems.
	- Allow for getting files from tftp server that does not run a
	  bootpd/dhcpd.
	- Fix a great deal of incorrect format strings which could cause
	  yaboot crashes.
	- Fix all filesystems to properly return error conditions, and
	  report those error conditions (instead of just saying `image not found').
	- Add `help' command to yaboot which prints out basic usage information.
	- General cruft removal and code cleanup.
	- Makefile cleanup, make filesystems configurable.
