This is because while we made the CFLAGS get some new options, LDFLAGS never
got the same treatement, and we disabled %{_hardened_build} to avoid getting
its options in the TARGET_{C,LD}FLAGS variables.
This patch duplicates the infrastructure for {HOST,TARGET}_CFLAGS into
{HOST,TARGET}_LDFLAGS, and adds the %{_hardening_ldflags} and
%{_hardening_cflags} to both HOST_{C,LD}FLAGS.
Additionally, it fixes the CPPFLAGS definitions, since rpm doesn't define any
CPPFLAGS at all, and makes the -I$(pwd) be there exclusively, not on CFLAGS as
well, since they're always used in concert.

There's no point on executing the script if GRUB_ENABLE_BLSCFG has already
been set. Currently was checking if an user explicitly set it to false to
avoid enabling the BLS configuration, but it should also be avoided if was
already set to true by a previous package update or during installation.

The blscfg module isn't compatible with the GRUB core.img installed by any
release older than Fedora 21.
This is because the blscfg module calls to the grub_file_size() function to
check if the BLS file size is correct, but the struct grub_file used as the
parameter for this function changed in the GRUB version used in Fedora 21.
So the function returns a wrong file size due the .size field offset being
different in the older GRUB from Fedora 20 and earlier.
This is causing all the BLS files to be ignored due having a wrong size and
leading to GRUB menu not being populated on boot.

os-prober 1.75 dropped all the code for handling device mapper
directly in favor of only supporting the use of grub2-mount.
Thus, we now need grub2-mount to be built and packaged so that
os-prober can depend on it. We ship it in the grub2-tools-minimal
package to avoid creating a dependency loop between grub2-tools and
os-prober.

GRUB has an user-space program emulator that allows to parse config files
and execute boot entries using the kexec tool. Add a grub2-emu subpackage
to install the emulator.
The subpackage is disabled on ppc64le architecture for now since grub2-emu
fails to build there.

The GRUB configuration is switched to BLS using the grub2-switch-to-blscfg
script, which is installed by the grub2-tools package. Among other things,
the script copies the blscfg module from the /usr/lib/grub/$arch directory
to /boot/grub2/$arch.
This is done because for non-UEFI installs (i386-pc and powerpc-ieee1275)
the GRUB core and modules aren't updated on package upgrade, so the blscfg
module won't be the latest that contains the current BLS support.
But the grub2-switch-to-blscfg script is currently executed in grub2-tools
%post scritplet, which means that if the grub2-tools package is installed
before the grub2-pc-modules package (that installs the blscfg module), the
grub2-switch-to-blscfg script won't copy the latest version of the module.
This will make systems to fail to populate the GRUB menu, since its config
will already be migrated to BLS but the blscfg module won't be the latest.
So to make sure that the latest blscfg module is copied regardless of the
grub2-tools and grub2-pc-modules packages install order, run the switch
script in a grub2-tools %posttrans so it's executed at the end of the RPM
transaction once all the packages have been installed.

The generated menu entries have a --users $grub_users option but this will
fail on old versions of GRUB, since it expects the --users option argument
to either be a constant or a variable that has been set.
The latest GRUB version fix this but the GRUB core isn't updated on a GRUB
package update, so this will cause the entries to not be shown in the menu
after a system upgrade.
Since can cause issues and because the entries that weren't generated from
the BLS snippets didn't have the --users option either, just don't add it.

Commit bfc756f8d86 ("Set blsdir if the BLS directory path isn't one of the
looked up by default") attempted to set blsdir if /boot/loader/entries was
not the real path of the directory containing the BLS snippets. Which may
be the case if for example /boot/loader/entries is in a btrfs subvolume.
But in the case of ostree, /boot/loader is a symlink to the directory with
the entries for the current deployment. So with ostree the blsdir will be
wrongly set, since GRUB is able to follow the symlinks just fine. In fact,
it has to follow the symlink since otherwise GRUB will always use the BLS
files for the deployment that the symlink pointed out when blsdir was set.
So only set blsdir if /boot/loader/entries is in a btrfs or zfs partition.

The switch to a BLS configuration was made before in the grubby package

The grub2-efi package create a /boot/grub2/grubenv symlink that points to
/boot/efi/EFI/fedora/grubenv that's where the real grubenv file is looked
up by GRUB on an EFI installation.
But currently if the grub2-efi is installed on a legacy BIOS install, it
will overwrite an existing /boot/grub2/grubenv file with a broken symlink.
So mark it as %config(noreplace) to avoid loosing an existing grubenv.

In rhbz#1638405, we worked around the issue of an existing initramfs
being in the way by removing it if it's older than the kernel we're in
the process of installing.
But it was buggy and only worked with some filesystem layouts and paths, and
also possibly had some issues with file creation times causing the shell -ot
comparison to fail in some cases.
This patch changes it to remove the existing kernel (as well as other
related files) in the case that it's going to do the copy, and also fixes the
path issues.
