Hello!

Have tried to test Kubic on VirtualBox VM and faced with a problem of Kubic
installation (see screenshot on Twitter-link below). One knows VirtualBox VM
VDI disk is 8 GB by default.

And the problem was that Kubic needs > 16 GB to be successfully installed. 16
GB doesn't work. 17 GB is already OK.

See dialogue here: https://twitter.com/500mk500/status/977722519942762496?s=19

While Kubic is the set of pre-assembled packages with hardly constant minimal
HDD requirements instead of classic openSUSE Leap/TW distro, HDD capacity is
going to be much more critical for Kubic. And let Kubuc be able to check HDD
capacity _before_ its installation process.

Idea for Realization:
=================
The most obvious way is to have an option in boot menu like 'Check Hard Disk
Requirements before Installation'. And this option must be first by default and
highlighted by cursor.
=================

Expectations:
=================
1. 'Check Hard Disk Requirements before Installation' should start initramfs,
udev and hwinfo.

2. Then to parse hdd capacity.

3. If hdd < 17 GB, then return message: "Hard Disk Capacity is %number%. You
need to have >=17GB to install openSUSE KubicProject successfully". By clicking
OK, system returns to boot menu.

4. If hdd >= 17 GB, then return message: "Hard Disk Capacity is %number%. You
can install openSUSE KubicProject successfully from boot menu". By clicking OK,
system returns to boot menu.
=================

In general way, 'Check Hard Disk Requirements before Installation' is like to
'More' --> 'Check Installation Media' mechanism to its logic.

Another Way for Realization:
=================
Not to modify boot menu and work on hdd capacity comparison to >=17 GB on
hardware detection step, when 'Installation' option is chosen.

If hdd < 17 GB, then return message: "Hard Disk Capacity is %number%. You need
to have >=17GB to install openSUSE KubicProject successfully. Installation is
stopped. Press any key..." By user's pressing any key, system returns boot
menu.
=================

Please, consider! Thanks!
