DOMOUNTROOTHOOKS(9) OpenBSD Kernel Manual DOMOUNTROOTHOOKS(9)NAMEdomountroothooks - 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.
