Bug#1064624: Hard to short-stroke an encrypted drive

[Matthew Wilcox <willy@infradead.org>]

Package: debian-installer

The partitioner "guided partitioning" offers me:

 - use the largest continuous free space
 - use entire disk
 - use entire disk and set up LVM
 - use entire disk and set up encrypted LVM

I want "use largest contiguous space and set up encrypted LVM".
That would let me reserve 200GB of my SSD as unencrypted free space,
which will improve the write endurance of my SSD.


Also once I start partitioning, eg, "and set up LVM", I can't delete the
partitions again.  Well, I can, but I have to switch to a terminal,
run dmsetup remove_all.  Which sometimes confuses the partitioner and it
gets stuck printing "??? ???"  If that happens, I can neither "go back",
nor "continue".
