	46	.Sh DESCRIPTION
	47	.Sy Power fail and crash recovery.
	48	Normally, the system will reboot itself at power-up or after crashes.
	49	An automatic consistency check of the file systems will be performed
	50	as described in
	51	.Xr fsck 8 .
	52	and unless this fails, the system will resume multi-user operations.
	53	.Pp
	54	.Sy Cold starts
	55	The SPARC system currently uses the SunOS bootstrap loaders.
	56	This will be changed in a future version of the system.
	57	The SunOS boot will attempt to load
	58	.Pa vmunix
	59	from partition A of the boot device,
	60	which must currently be an ``sd'' disk.
	61	.Pp
	62	The
	63	.Op Fl s
	64	flag to the SunOS boot loader will being the system up in single-user mode.
	65	The
	66	.Op Fl d
	67	flag to the SunOS boot loader will bring the system up in debug mode.
	68	Here it waits for a kernel debugger connect; see
	69	.Xr kgdb 8 .
	70	Other flags are currently ignored.

	88	The use of Sun disk labels, without the ability to write them,
	89	is problematic.
