No. devfs is broadly equivalent to the devfs in Solaris. It is a
synthetic filesystem which maintains device nodes. Kernel drivers are
now able to create their own device nodes using the make_dev(9) API.
You should no longer need to maintain a /dev directory; devfs does
it for you.
You probably do wish to read devd(8) however -- this is a daemon which
manages the devfs in response to NEWBUS messages from the kernel.
