Thank you very much!

So in the case of codes below:

static ulong
sdiocmd(int cmd, ulong arg)
{
	ulong r;

	qlock(&sdiolock);
	if(waserror()){
		if(SDIODEBUG) print("sdiocmd error: cmd %d arg %lux\n", cmd, arg);
		qunlock(&sdiolock);
		nexterror();
	}
	r = sdiocmd_locked(cmd, arg);
	qunlock(&sdiolock);
	poperror();
	return r;

}

static ulong
trysdiocmd(int cmd, ulong arg)
{
	ulong r;

	if(waserror())
		return 0;
	r = sdiocmd(cmd, arg);
	poperror();
	return r;
}

we see two lines of waserror(), and trysdiocmd() calls sdiocmd()
which also includes waserror() line.  In this case which of the waserror()
will be called when error() occurs somewhere?

By the way, aux/wpa demands the factotum preset the wpapsk, essid and password.
It is possible to setup wifi after the system booted-up.

However, to get the / filesystem from a file server to boot the system,
which is in my case, how I can preset the factotum for wpapsk before the root filesystem
mounted?   To mount the root I need to connect to the file sever, but I have no wifi setup yet.

It sound like too much novice, however, I seem to be struggling around it.
