Let me say in advance that it is lacking any form of error checking. I should
also find some way to determine which disk we're booting from, since that is
the only disk that makes sence to read the config from.
{
char *bootdev[]={"/dev/da0","/dev/da1",NULL};
start_config(0);
lock_config();
vinum_scandisk(bootdev,sizeof(bootdev)/sizeof(bootdev[0]));
unlock_config();
finish_config(0);
save_config();
}
I've added this bit to the end of vinumattach() which seems to be working.
However the routines in kern/vfs_conf.c are unable to mount a vinum volume. Haven't
had time to really look into that.
