This isn't necessarily applicable: in Plan 9, almost everything was a
filesystem. Does Plan 9's use of #e mean we should ditch the Unix-style
environment?

On the flip side, the folks complaining about devfs in the kernel vs.
Solaris's version being in "user space" need to remember that Solaris's
device tree is initially built by the OpenBoot PROM, and the kernel
trivially constructs /devices from that. If you'll show me where this
functionality is in PC BIOSes, I'll consider it a valid argument.
