.Sh DESCRIPTION
|
|
The
|
|
.Tn NetBSD
|
|
kernel, an ordinary executable file,
|
|
is placed into chip memory by bootstrap.
|
|
Upon startup, the system reorganizes memory to suit the needs of
|
|
the hardware configuration found and copies itself to virtual memory,
|
|
thus it is not designed to
|
|
be restartable without being reloaded on reboot.
|
|
Each time it is to be bootstrapped, it must be reloaded, usually from
|
|
a disk file.
|
|
.Pp
|
|
.Sy Rebooting a running system .
|
|
When a
|
|
.Tn NetBSD
|
|
kernel is running and a reboot is desired,
|
|
.Xr shutdown 8
|
|
is normally used.
|
|
If there are no users then
|
|
.Nm reboot
|
|
can be used.
|
|
Reboot causes the disks to be synced and allows the system
|
|
to perform other shutdown activities such as resynchronizing
|
|
hardware time-of-day clocks.
|
|
.Pp
|
|
Options to reboot are:
|
|
.Bl -tag -width indent
|
|
.It Fl n
|
|
option avoids the sync. It can be used if a disk or the processor
|
|
is on fire.
|
|
.It Fl q
|
|
reboots quickly and ungracefully, without shutting down running
|
|
processes first.
|
|
.El
|
|
.Pp
|
|
.Nm Reboot
|
|
normally logs the reboot using
|
|
.Xr syslog 8
|
|
and places a shutdown record in the login accounting file
|
|
.Pa /var/log/wtmp .
|
|
These actions are inhibited if the
|
|
.Fl n
|
|
or
|
|
.Fl q
|
|
options are present.
|
|
.Pp
|
|
.Sy Cold starts .
