RB_AUTOBOOT 0x0000|
The default, causing the system to reboot in its usual fashion.
| RB_ASKNAME 0x0001|
Interpreted by the bootstrap program itself, causing it to
prompt on the console as to what file should be booted.
Normally, the system is booted from the file
``xx(0,0)netbsd'',
where
xx
is the default disk name,
without prompting for the file name.
| RB_DUMP 0x0100|
Dump kernel memory before rebooting; see
savecore(8)
for more information.
| RB_HALT 0x0008|
the processor is simply halted; no reboot takes place.
This option should be used with caution.
| RB_POWERDOWN 0x0808
This option is always used in conjunction with
RB_HALT,
and if the system hardware supports the function, the system will be
powered off, otherwise it has no effect.
| RB_INITNAME 0x0010
An option allowing the specification of an init program (see
init(8))
other than
/sbin/init
to be run when the system reboots.
This switch is not currently available.
| RB_KDB 0x0040
Load the symbol table and enable a built-in debugger in the system.
This option will have no useful function if the kernel is not configured
for debugging.
Several other options have different meaning if combined
with this option, although their use may not be possible
via the
reboot()
call.
See
ddb(4)
for more information.
| RB_NOSYNC 0x0004|
Normally, the disks are sync'd (see
sync(8))
before the processor is halted or rebooted.
This option may be useful if file system changes have been made manually
or if the processor is on fire.
| RB_RDONLY 0x0080|
Initially mount the root file system read-only.
This is currently the default, and this option has been deprecated.
| RB_SINGLE 0x0002
Normally, the reboot procedure involves an automatic disk consistency
check and then multi-user operations.
RB_SINGLE
prevents this, booting the system with a single-user shell
on the console.
RB_SINGLE
is actually interpreted by the
init(8)
program in the newly booted system.
When no options are given (i.e.,
RB_AUTOBOOT
is used), the system is
rebooted from file ``netbsd'' in the root file system of unit 0
of a disk chosen in a processor specific way.
An automatic consistency check of the disks is normally performed
(see
fsck(8)).
| RB_STRING 0x0400
bootstr
is a string passed to the firmware on the machine, if possible, if this
option is set.
Currently this is only implemented on the sparc and the sun3 ports.
| RB_USERCONF 0x1000|
Initially invoke the
userconf(4)
facility when the system starts up again, if it has been compiled into
the kernel that is loaded.
