I would have agreed with you before glibc required tmpfs to pass it's
checks and shared memory became common. Are you aware of any popular
distro that *doesn't* include tmpfs in the default configuration?
The reason is that the bootscripts use tmpfs, so when explaining the
manual mounting of /dev at the beginning of chapter6 it would be nice to
explain it how it will be done at bootup without having to explain why
we aren't doing it that way during the manual phase.
This might be a good time to specify enabling tmpfs in the kernel page
where hotplug is explicitly mentioned. I'll BZ this.
