[Bug 1596968] Re: fail to activate fcp device for installation

[Dimitri John Ledkov]

Please perform installation using "apt-setup/proposed=true" in the param
file and confirm that installation on an LPAR with 100+ zfcp devices
visible is now possible.

I have performed installation on our LPARs without regressions using
1.0.2ubuntu1.1 s390-zfcp package from proposed. However, the mainframe I
am performing this test on has insufficient amount of zfcp devices to
trigger the originally reported bug.
