Re: Dell Wyse T10 / T50

This is how I've created the USB rootfs:

root@koen-ThinkPad-X220:/# mkfs.ext3 /dev/sdc1 -L rootfs
mke2fs 1.44.1 (24-Mar-2018)
/dev/sdc1 contains a ext3 filesystem labelled 'rootfs'
        last mounted on /media/koen/rootfs on Sun Jul 29 09:15:41 2018
Proceed anyway? (y/N) y

I don't get output on serial only on screen so I won't be able to capture it all unfortunately. I'll type out the bit that is visible when the kernel panic happens in the next post.
