run all mountroot hooks
SYNOPSIS
#include
<sys/types.h>
#include <sys/systm.h>
void
domountroothooks
(void);
DESCRIPTION
The
domountroothooks
()
function invokes all mountroot hooks established using the
mountroothook_establish(9) function. Mountroot hooks are
called in order, i.e., the mountroot hook established first will be called
first.
This function is called from
main
() with
interrupts turned on. It is called immediately before the system configures
its root and swap devices, but fully after all normal autoconfiguration.
This can be used to let device subsystems needing delayed configuration
(e.g., due to very long initialization times) still provide the root device.
The I2O system, implemented by the
iop(4) and
ioprbs(4) drivers, is a good example.
Mountroot hooks are, like shutdown hooks, implemented via the more general dohooks(9) API.
