The proposed changes concern two steps:
First, when creating the RAID configuration, have a GPT partition
table type (this is not necessary, but more natural with UEFI).
Also, leave some space, either for the EFI partitions or the BIOS
boot partitions, outside the Software RAID.
Secondly, when installing the bootloader, make sure the correct
boot partitions are created or relocated.

If an md device is restarted, there is a chance, depending
on the OS, that the partition may not be found upon start
of the md device.
Instead, we should always rescan after re-assembling the raid
device.

Somewhat common are dual boot images that have both a MBR loader
and the contents required for a UEFI boot, as largely the pointer
to where to begin reading the rest of the boot loader occurs in
the first few hundred bytes on disk which redirects the disk to
begin reading from a known address.
This goes sideways on UEFI machines where this method of booting
is not recognized nor supported. Thus we need to return false when
we encounter this state.

With the fix to the uefi code path so secure boot works properly
and is not accidently stomped on, we forgot to rescan the device
and force the partition table to update, which is vital for iscsi
based deploys.

This patch changes the workflow for whole disk images when using uefi.
If we can identify the bootloader and it's valid we can update using
efibootmgr since grub2-install have problems specially on secure boot
mode.
We also updated the regex to search for the uefi partition on the disk,
since in some cases the parted command output can be without the FS
for the partition with esp Flag.

Lets not do silly things and if the disk looks bootable,
and we're not trying to do UEFI, then let us assume the
proper thing will occur upon power-up.
Looks at the boot sector data and if an executable is
found in the first 218 bytes, then it bypasses loading
a boot loader.
Also adds a dependency on the "file" linux distribution
package.

When deploying an image to a software raid array, it is currently
required that the deployed image assembles the md arrays automatically
so that the rootfs can be mounted. In order to remove this
requirement/limitation on the deployed image we can add rd.md.uuid to
the kernel command line with the raid array's uuid.

md device, find the underlying holder disks and configure grub
on them.

grub-mkconfig runs a lvs command that attempts to access /run/lvm
once for each block device, currently it times out after 10 seconds
for each device and moves on. Multiple 10 second delays become
a problem (causing IPA API timeouts) when multiple block devices
are present. Bind mounting in /run avoids the delay and the
timeouts.

Installs the grub bootloader to the PreP Boot partition when the
prep_boot_partition_uuid is provided. This is required when
booting a partition image locally on ppc64* systems.
This change also passes the cpu_arch along to work_on_disk so
that the PReP partition is created when partitioning disks for
local boot on ppc64* systems,

there is no guarantee that 'bash' is present in a user's image,
while 'sh' as system shell must be there.
As we do not use any bash-specific syntax (just starting commands in a
subshell) when installing the bootloader from chroot-ed user image,
let's be more supportive and use 'sh' instead of 'bash' for that.

In systems where the nvram may have been reset, add
\EFI\BOOT\BOOTx64.EFI to the EFI system partition so that
the image continues to boot. This will be particularly useful
if the NVRAM wasn't written correctly or if the baremetal
server is be simulated on virt and the NVRAM was been reset
on start (as is the case in libvirt).

This patch updates the _install_grub2 function in image.py
so that we use 'mount -t sysfs' instead of bind mounting
the hosts /sys into the chroot.
This resolves issues which can occur with unmounting
the chroot mounts where 'target is busy' errors
may occur when you are debugging things with a serial
console.
