It doesn't.

I copied them with rsync, using the option that copies one file system
only; i.e. does not cross file system boundaries. That's why there
is no /ascii/dev -- the original /dev was a mounted file system
created by I presume udev.

Which is why I thought I had to create the mount point in ascii.
Now I suspect I'd also have to create /sys /proc and /run as
additional mount points?

Or should I start over, booting refracta instead of my new system and
using refracta to copy everything when everything isn't the working
system?
