qemu 2.12 removed the -usbdevice option. Use a more modern spelling
instead, in line with other USB-related tests.

SeaBIOS 1.11.0 added support for VGA emulation over a serial port, which
interferes with grub-shell. Turn it off.

If something else on the system is using loopback devices, then the
device that's free at the call to `losetup -f` may not be free in the
following call to try to use it. Instead, find and use the first free
loopback device in a single call to losetup.

"F2FS (Flash-Friendly File System) is flash-friendly file system which was merged
into Linux kernel v3.8 in 2013.
The motive for F2FS was to build a file system that from the start, takes into
account the characteristics of NAND flash memory-based storage devices (such as
solid-state disks, eMMC, and SD cards).
F2FS was designed on a basis of a log-structured file system approach, which
remedies some known issues of the older log structured file systems, such as
the snowball effect of wandering trees and high cleaning overhead. In addition,
since a NAND-based storage device shows different characteristics according to
its internal geometry or flash memory management scheme (such as the Flash
Translation Layer or FTL), it supports various parameters not only for
configuring on-disk layout, but also for selecting allocation and cleaning
algorithm.", quote by https://en.wikipedia.org/wiki/F2FS.
The source codes for F2FS are available from:
http://git.kernel.org/cgit/linux/kernel/git/jaegeuk/f2fs.githttp://git.kernel.org/cgit/linux/kernel/git/jaegeuk/f2fs-tools.git
This patch has been integrated in OpenMandriva Lx 3.

On such a filesystem, inodes may have EXT4_ENCRYPT_FLAG set.
For a regular file, this means its contents are encrypted; for a
directory, this means the filenames in its directory entries are
encrypted; and for a symlink, this means its target is encrypted. Since
GRUB cannot decrypt encrypted contents or filenames, just issue an error
if it would need to do so. This is sufficient to allow unencrypted boot
files to co-exist with encrypted files elsewhere on the filesystem.
(Note that encrypted regular files and symlinks will not normally be
encountered outside an encrypted directory; however, it's possible via
hard links, so they still need to be handled.)
Tested by booting from an ext4 /boot partition on which I had run
'tune2fs -O encrypt'. I also verified that the expected error messages
are printed when trying to access encrypted directories, files, and
symlinks from the GRUB command line. Also ran 'sudo ./grub-fs-tester
ext4_encrypt'; note that this requires e2fsprogs v1.43+ and Linux v4.1+.

1. Make sure files are not multiple of block size. This will ensure tail packing
for squash4 and may also trigger more codes paths in other filesystems.
2. Call mksquashfs with -always-use-fragments to force tail packing.
proot creates hidden files with .proot prefix and name
derived from real file name. So decrease file name length
and path depth. For some reason depth 85 also results in
undeleteable directory, so use 84 instead of 85.
The firmware and the OS may disagree on the disk configuration and size.
Although such a setup should be avoided users are unlikely to know about
the problem, assuming everything behaves like the OS. Tolerate this as
best we can and trust the reported on-disk location over the firmware
when looking for the backup GPT. If the location is inaccessible report
the error as best we can and move on.
Portions of the code attempted to handle the fact that GPT entries on
disk may be larger than the currently defined struct while others
assumed the data could be indexed by the struct size directly. This
never came up because no utility uses a size larger than 128 bytes but
for the sake of safety we need to do this by the spec.
