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

[Dimitri John Ledkov]

@hws

This is not a bug per-se, as LVM itself uses kernel drive names in the
metadata, and the output shown in the LVM partitioner menu is the same
as shown by LVM2 utils, $ sudo pvs

Please remove any target for this issue (e.g. targetmilestone-inin--),
because there is no immediate way to resolve this. If you wish to
improve LVM2 tooling, please contact LVM2 upstream to make all utilities
(vgs, pvs, vgchange, etc.) to use alternative symlink names, instead of
real kernel device names.

I do not believe it makes any sense for installer code to post-process
output of $ sudo pvs, trying to mangle it and reconcile it with ids.
Especially since installed systems will not have any tooling (e.g. pvs)
that will also show output with ids.

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.
