>Description:
devd uses space as delimiter. However, sometimes spaces appear in description.
For example, consider such debug log:

Processing event '!system=DEVFS subsystem=CDEV type=CREATE cdev=ntfs/SAMSUNG I'
Pushing table
setting system=DEVFS
setting subsystem=CDEV
setting type=CREATE
setting cdev=ntfs/SAMSUNG
Processing notify event
Testing system=DEVFS against ^DEVFS
Testing subsystem=CDEV against ^CDEV
Testing type=CREATE against ^CREATE

In fact, the label of the ntfs partition is "SAMSUNG I", so cdev should be "ntfs/SAMSUNG I", but devd sets cdev to ntfs/SAMSUNG, which is wrong.

>How-To-Repeat:
Insert any disk with a space in the label, and see the debug output of devd.
>Fix:
Maybe it is /sys/kern/kern_conf.c which should be changed, since devd can realize double quotes(").
