Bug 429197

Description of problem:

Say that one creates a RAID array from a number of disks and for
whatever reasons a particular partion layout is required of every
of those disk.  So one start with, say, /boot and unchecks all
disks but sda, created that partitions and goes to the next one.
Oops!  All available disks are checked in by a default for that
one again.  So uncheck, uncheck, uncheck ... and da capo al fine.
With 24 disks around (the real life scenario) this is getting old
pretty quickly.

A way to make anaconda to remember current disk choices until
explicitely changed would be extremely desirable.  The second
best option would be a switch to make _all_ disks unselected by
default when starting with a new partition.

Yes, personally in such situation I would rather script partitioning
across all devices (although a need to specify END when creating
partitions in parted, and this detail that END cannot be set
"too high" - or at least by not too much, is a serious PITA) but
various people doing actual installations are really hard to
persuade to take that approach; especially when GUI tools are
somehow available.
