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.

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