Description of Problem:
When creating the lowest partition on a new disk Disk Druid warns about
necessity of leaving an extra space for a boot block but how to achieve
that effect is far from clear. No option to specify the lowest cylinder
either in "New" or in "Edit" dialogs for a partition. How a newbie
is supposed to guess that "Edit" on a "Free space" will make that possible?
Probably only by random tries. Also in a text mode that dialog allows
to cut-out a such new partition with a size specified in megabytes; but
in graphics mode one can only give the last cylinder leaving calculations
to an already spooked user.
In the current images I'm using, both autopartitioning and manual intervention
with disk druid will automagically create the space at the front of the disk for
the bootloader without the need for someone to create it
