Re: [9fans] installing on a usb disk

[Francisco J Ballesteros <nemo@lsub.org>]

Ok. Then it's as expected.
In this usbdb, usb/disk is built into usbd.
That means that usbd will spawn a driver for disk as soon as it sees
a disk plugged in. If you run usb/disk on your own, there will be no unhandled
disks left for it and it should say that there are no disks and exit.

Regarding the mount, yes, the fs from usbd is to be mounted also at /dev
for usbfat and others to use. You might add an entry to your namespace file
if it's not mounted by default.
