access usb stick from with initramfs

[chesty]

Hey,

I'm playing around with overlay root filesystem mount, and got it working using tmpfs as the overlay, but I want to use a usb stick, and I can't work out how to make a usb stick available inside a initramfs during boot.

During boot, inside the initramfs,
there's no /dev/sda
lsusb sees the stick

once it's booted, /dev/sda is available and I can mount /dev/sda1

got any ideas?

weird, I started copying data to the stick and was getting errors, so swapped it out and now I see the new one inside initramfs.

I think I can close this question and open an X file
