Hello usb developers.
I am working on booting linux from USB stick.
Q1.
It takes several secs to recognize a usb stick after kernel booted.
This prevents to boot directly usb stick without initrd.
you need very foolish boot script like
/linuxrc on initrd:
#!/bin/sh
sleep 3 # wait for usb recognized.
exit # falls down to real root.
Is there any way to recognize usb immediately?
for example, hard coding parametes in kernel or such.
at least, is there any patch to insert wait loop to
kernel/main/init.c ?
Q2.
I tested with several sticks and found some sticks are /dev/sda,
some are /dev/uda as you might have already know this.
What determines this? What is the difference between the sda stick
and uba stick?
I also found the uba stick is recognized prior to sda. Is this
feature? or just coincident?
