I fixed it in a way that I'm completely happy with, so this now Just 
Works, and doesn't require the path to exist outside the sandbox.

I've published 0.99.5 and updated wip/bob, and tested this with a 
netbsd-9 sandbox.  Here's what I did:

  - Unpacked daily netbsd-9 sets from nycdn to /data/netbsd-9-x86_64

  - Ran `what netbsd` to figure out it was 9.4_STABLE.

  - Installed libkver and copied libkver.so.1 to /data/netbsd-9-x86_64/lib

  - Modified config.lua to mount the base system directories from this path
    rather than the system mounts.

  - Set LD_PRELOAD="/lib/libkver.so.1" and LIBKVER_OS_RELEASE="9.4_STABLE" in
    vars.

Seems to work:

   # uname -rsm; gcc -dumpversion
   NetBSD 10.1 amd64
   10.5.0

   # bob dev
   Creating sandbox... done (1.4s)
   Entering sandbox /data/chroot/0...
   sandbox:0 /# uname -rsm; gcc -dumpversion
   NetBSD 9.4_STABLE amd64
   7.5.0

Cheers,
