Since file copy programs are easy to write, why not write one that
will copy to/from a rumpo device.

Alternatively, for open, feed into a rump libc stub that looks at the
start of the pathname (and maybe an env variable) to work out
whether to open a local or global file.
For most uses this will be fine.
You might need to open a real file to allocate an fd ...
