Bug#657955: partman-nbd: nbd-root install / mkinitramfs: missing /sys/block entry)

[ipod@viop.ca]

Dear maintainer,

It seems that the bug appears only in installations of testing/sid, because:

After some more trials, what DOES work for NBD-root setup in
debian-installer, is:

AT: Debian GNU/Linux installer boot menu
    -hit TAB; type "modules=partman-nbd"; hit ENTER

AT: [!!] Select a language
    -hit TAB; "<Go Back>" is highlighted; hit ENTER

AT: [!] Debian installer main menu
    -arrow key down to "Change debconf priority"; hit ENTER

AT: [!!] Change debconf priority
    -arrow key down to "low"; hit ENTER

...carry on with installation as normal, until:

AT: [?] Choose a mirror of the debian archive (Debian version to install:)
    -the selection should be "squeeze  -  stable"; hit ENTER

...carry on with installation as normal, until:

AT: [.] Debian installer main menu (Detect disks)
    -skip "Detect disks"; arrow key down to "Partition disks"; hit ENTER

AT: [?] Debian installer main menu (Choose an installation step)
    -hit TAB; "<Go Back>" is highlighted; hit ENTER;

AT: [!!] Partition disks (This is an overview of your currently selected...)
    -the selection should be "Configure the Network Block Device"; hit ENTER

AT: [!!] Partition disks (NBD configuration action:)
    -the selection should be "Connect a Network Block Device"; hit ENTER

AT: [!!] Partition disks (Network Block Device device node:)
    -the selection should be "/dev/nbd0"; hit ENTER

AT: [!!] Partition disks (Network Block Device server:)
    -type the IP address or hostname of your NBD server, e.g. 192.168.0.110

AT: [!!] Partition disks (Network Block Device port or name:)
    -type the port number that your NBD server is listening on, e.g. 12345

AT: [!!] Partition disks (NBD configuration action:)
    -arrow key down to "Finish and return to the partitioner"; hit ENTER

...carry on with installation as normal, until:

AT: [.] Debian installer main menu (Install the GRUB boot loader on a hard
disk)
    -arrow key down to "Continue without the boot loader"; hit ENTER
    -(make sure to note the kernel parameters it gives you)

...carry on with the installation as normal.
