I find the dialog rather misleading. You say "amount of *disk space* to be 
used for guided partitioning", but what you do (IIUC) is only to leave 
part of the *VG* unused: you still create a VG that fills the whole disk. 
The "or if you add more disks" also makes no sense in the context of your 
patch.

I wonder if it would not be better to allow users to specify to leave a 
_partition_ of a certain size unused. That would also make it usable for 
non-LVM guided partitioning and is a much better match for the 
description in your template.
