[Bug 906722] Re: root partition is not being grown

Doesn't look to me like any changes to util-linux are called for here.
I think cloud-init should just have a versioned dependency on util-linux
(>= 2.20) and call sfdisk with the --no-reread option, since that's what
you want.  (You know that the disk is always going to be mounted in this
case, and that you always want to resize if necessary, so this check
doesn't seem to serve any purpose here.)

If that doesn't work for whatever reason, feel free to reopen against
util-linux of course.

  root partition is not being grown

Bug description:
  Upon booting an openstack instance of precise-i386-20111219-failed-console.log, I found that the root filesystem had not been resized as it normally would have been.
  This occurred on both i386 and amd64.

  Kernel output contains something like:
  Begin: Running /scripts/local-bottom ... [    1.852884] FDC 0 is a S82078B
  [    1.862945] 8139cp 0000:00:03.0: eth0: RTL-8139C+ at 0xf840a000, 02:16:3e:21:8a:47, IRQ 11
  [    1.877189] 8139too: 8139too Fast Ethernet driver 0.9.28
  ***** WARNING: Resize failed, attempting to revert ******
  BLKRRPART: Device or resource busy
  The command to re-read the partition table failed.
  Run partprobe(8), kpartx(8) or reboot your system now,
  before using mkfs
  ***** Appears to have gone OK ****
  GROWROOT: FAILED: failed to resize
  Re-reading the partition table ...
  Begin: Running /scripts/init-bottom ... done.

  It should show something like:

  Begin: Running /scripts/local-bottom ... [    1.314676] 8139cp 0000:00:03.0: eth0: RTL-8139C+ at 0xf840a000, 02:16:3e:3e:94:65, IRQ 11

  This worked as recently as ubuntu-precise-daily-i386-server-20111213.
