mdadm is know to be broken when installing in a chroot without having
/proc mounted, maintainer should check for /proc in the maintainer
scripts (and don't do anything if /proc isn't there, hence reassigning
to mdadm).

temporary workaround: install mdadm when you've booted the live system,
then it works.

and yes, mounting /proc in the chroot is not a solution, because:

  * there are cases where it is not possible to unmount a mounted /proc
    in a chroot if certain (unkillable) processes access it. since only
    rebooting the whole system helps, we do not mount /proc in the
    chroot.

  * mdadm maintainer scripts do read out /proc to scan for raid devices.
    if your host system has a raid, you end up with a preconfigured
    mdadm in your live-system, which is not (or not always
    intentionally) what you want.

Daniel
