[Bug 1436020] Re: Multipath: underlying disks are listed for partitioning on systems w/ 24+ disks

[Mauricio Faria de Oliveira]

BTW, this may look like a superfluous thing, but actually isn't.

The listing/consideration of underlying devices by the partitioner may trigger the problem #6 described in bug 1430074,
which is the PReP flag being lost from the boot device.. so the installed system won't boot.

Title:
  Multipath: underlying disks are listed for partitioning on systems w/
  24+ disks

Status in partman-base package in Ubuntu:
  New

Bug description:
  On top of the fix in LP: #1430074, there's a minor bit missing.

  It doesn't hide all underlying disks in the partitioning dialog if
  there's 24+ underlying disks (i.e., enough for sdaa and so on to show
  up).

  It happens because, in that case, 'multipath -l' now puts 2 spaces
  betweek disk and major:minor for the sd[a-z] disks, and only 1 space
  for sd[a-z][a-z].

  Patch attached.
