The code is in sys/stand/boot.c
devboot(bootdev, cmd.bootdev);
strlcpy(cmd.image, kernelfile, sizeof(cmd.image));
cmd.boothowto = 0;
cmd.conf = "/etc/boot.conf";
cmd.addr = (void *)DEFAULT_KERNEL_ADDRESS;
cmd.timeout = boottimeout;
if (upgrade()) {
strlcpy(cmd.image, "/bsd.upgrade", sizeof(cmd.image));
printf("upgrade detected: switching to %s\n", cmd.image);
isupgrade = 1;
}
st = read_conf();
Figure out how to build and install. It is not hard to test.
