Re: [9fans] running plan9 : an ideal setup?

[Dante <subscriptions@posteo.eu>]

Hi Mats,

Look in the /dev directory (ls /dev).
If you only have the boot device and an additional USB drive (in your
case, an USB-to-SD adapter),
the boot device shall be /dev/sdM0 and
the USB/SD device shall be /dev/sdU0.0

Kind Regards,
Dante
