Linux kernel have some memory overhead depending on maxmem. Dom0 isn't
meant to use that much memory (most should be assigned to AppVMs), so on
big systems this will be pure waste.

QubesOS/qubes-ossues#1018
Livecd-creator is one more example of program which happily installs
whatever downloads from the network, without any verification
(repository metadata consistency doesn't count)...
Patches sent upstream here:
https://github.com/rhinstaller/livecd-tools/pull/14
Anaconda requires /etc/sysconfig/network-scripts directory (even if
empty). Do not remove it, because if wouldn't be recreated if we omit
ifcfg dracut module.
Since livecd-tools doesn't support starting Xen in EFI mode, most of its
EFI support is rewritten here (overriden in LiveEFIImageCreator, based
on imgcreate.LiveImageCreator).
This all is still temporary solution, until Xen will have mutiboot2+EFI
support - then almost standard configuration could be used (almost the
same grub config as for legacy boot). So keep the changes here, and when
the proper solution would be implemented, pursue to having it upstream.
QubesOS/qubes-issues#794
xen.efi needs to call EFI services to access kernel and initramfs
images. For that it needs correct device handle. Grub set it to 'root'
device, regardless of which device was really used to load xen.efi.
Apparently all but first parameters are passed to xen.efi, so it is possible to
select which config section should be used. This makes xen.efi copy
unnecessary.
This comes with some overhead, at least at the beginning, because all
private images are copied there at system startup (instead of first
use). This uses about 450MB of RAM.
Still better than non-sparse private.img (2GB...).
