A few more problems with the rootfs:

- For some reason, the root filesystem comes up read-only (or rather,
  it is not remounted rw).  I can 'mount -o remount,rw /' just fine
  after boot, and it is 'defaults' in /etc/fstab, so I'm not sure
  exactly what is going wrong.

- The same error I had with F15: Because the Trim Slice has no hardware
  clock, it boots as 1970-01-01, which means https connections don't
  work, which breaks yum (because it defaults to an https URL).

- ssh access is broken, and the error is mysterious:

  Mar  2 17:16:16 fedora-arm sshd[704]: selinux sandbox not useful [preauth]
  Mar  2 17:16:16 fedora-arm sshd[704]: fatal: No supported key exchange algorithms [preauth]

  Doesn't appear to be related to the date/https problem, but the
  rootfs has selinux disabled (in /etc/selinux/config).
