In netbsd-6 it is just an internal name and the utilities have to use
the /dev/dkN (or /dev/rdkN) devices. Some understand dkN and expand
it to the proper pathname.

In netbsd-7, many utilities understand the string NAME=wedgename and
translate them to /dev/dkN accordingly. Some bootloaders also understand
a string wedge:wedgename to select a wedge as the root filesystem.

E.g. the RPI2 here uses the boot command line:

verbose fb=1920x1200 root=wedge:twitty-root console=fb

and uses the following fstab entries:

NAME=twitty-root        /               ffs     rw,log,nodevmtime       1 1
NAME=twitty-usr         /usr            ffs     rw,log          1 1
NAME=twitty-var         /var            ffs     rw,log          1 1
NAME=twitty-swap        none            swap    sw              0 0
NAME=bootcard/e         /boot           msdos   rw              1 1
NAME=twitty-home        /home           lfs     rw,nodev,nosuid 1 2
