[Bug 1558264] Re: Usability Partitioner menu does not display the real 4 digit device number

[Dimitri John Ledkov]

Indeed that would be nice, however currently d-i / partman operate
entirely in linux device names. However the lvm summary output is
ultimately driven by what `pvs` outputs from lvm tooling. Looking into
pvdisplay(8) manpage it seems there is no way for that to resolve and/or
output more descriptive (udev symlinked) names for devices.

Also given that d-i typically uses partitions as physical volumes one
would end up with: /dev/disk/by-path/ccw-0.0.0200-part1 as a label. Not
sure if that's better or worse than /dev/dasda1 for example.

Title:
  Usability Partitioner menu does not display the real 4 digit device
  number

Status in debian-installer package in Ubuntu:
  Confirmed

Bug description:
  == Comment: #1 - Hendrik Brueckner - 2016-03-10 05:53:02 ==
  Usability: Partitioner LVM menu displays dasdX devices.  The device name, the X in dasdX, depends on the order in which the DASDs are enabled (being set online).

  It would be better to display the device nodes by-path, for example,
  /dev/disk/by-path/ccw-0.0.e4a0.
