| 
| Sticking a freshly cleaned (dd if=/dev/zero of=/dev/sd0d bs=512 count=1)
| usb stick into the machine, labeling it (disklabel -re sd0) and trying to 
create an ufs filesystem on it (newfs /dev/sd0a) fails with:
| 
| newfs: /dev/sd0a: open for write: Device busy
| 
| Nothing obvious uses the usb stick. Rebooting changes nothing. Tested on Dell 
Latitude E6400 and a Dell Desktop GX280.
| 
| Accessing an usb stick which already contains an ffs filesystem works ok.
| >How-To-Repeat:
| 
| - put an usb stick into your 5.0_RC2 machine
| - dd if=/dev/zero of=/dev/sd?d bs=512 count=1
| - disklabel -re sd?
| - newfs /dev/sd??
| >Fix:


use /dev/rsd0a ?
