There is a grub2-set-default script that can be used to set the default
entry. It can take an entry id, title or index as a parameter so grubby
should be able to also lookup a default entry using the title on grub2.

Not all bootloaders used in Fedora have BLS support, for example extlinux
doesn't. So when using extlinux the old grubby tool has to be installed.
Currently the grubby-bls wrapper has precedence over the old grubby tool,
which means that even if grubby-deprecated is installed, the wrapper will
executed when calling grubby. Make the old grubby take precedence instead.

a BLS file is generated at build time and stored in /lib/modules/$kernel
but this default BLS file assumes that /boot is a mount point and so the
kernel and initrd paths are relative to the root of this boot partition.
This is not the case if /boot is not a mount point or if the bootloader
is zipl, since zipl expects the absolute path to be in the BLS snippet.
The kernel-install scripts takes care of this and modifies the BLS file
if needed, but grubby doesn't do that. So instead just generate the BLS
always even if there is one for the kernel version of the added entry.

The grub2 bootloader allows the BLS snippets fields to contain environment
variables instead of constants. This is useful for example to define the
kernel command line parameters only once in the grubenv file and set this
variable in the BLS snippets.
But this can be confusing for users when the information is printed by the
grubby script, so expand the variables if they can be looked up in grubenv.

The BLS file "linux" and "initrd" fields expect a relative paths from the
root of the partition that contains the kernel and initramfs. The grubby
tool was printing the value of thse fields and not their full path.
So if there is a partition and /boot is a mount point, he BLS would have:
linux /vmlinuz-4.18.0-38.el8.x86_64
initrd /initramfs-4.18.0-38.el8.x86_64.img
And grubby would print:
kernel="/vmlinuz-4.18.0-38.el8.x86_64"
initrd="/initramfs-4.18.0-38.el8.x86_64.img"
But the old tool used to print the full paths of the images, so should be:
kernel="/boot/vmlinuz-4.18.0-38.el8.x86_64"
initrd="/boot/initramfs-4.18.0-38.el8.x86_64.img"

Most bootloaders use the BootLoaderSpec "title" field to name the entries
in their boot menu. The zipl bootloader used the "version" field instead,
since it was wrongly assumed that the zipl boot menu didn't support names
that contained spaces, which are usually present in a BLS "title" field.
But this is not the case, names with space characters are supported by the
IPL and is just a constraint of the section heading in the zipl.conf file.
To be consistent with all the other bootloaders, zipl now uses the "title"
field to populate the boot menu entries from BLS files. So change grubby
to use the "title" field to set the default entry of the "version" field.

A BLS configuration is the default and in this case the installkernel-bls
script is used. For a non-BLS configuration the grubby-deprecated package
installs an installkernel that uses the new-kernel-pkg script.
So there is no need to check for GRUB_ENABLE_BLSCFG=true. Also, this check
is wrong for s390x and was causing the installkernel-bls script to no call
kernel-install on this platform.

By default the old grubby tool isn't installed anymore and it's part of
the grubby-deprecated package. Instead the grubby wrapper that modifies
BLS config files is installed for backward compatiblity with old grubby.
So on postinstall the bootloader configuration has to be changed to BLS
since non-BLS bootloader configuration won't be updated anymore without
the old grubby tool and the new-kernel-pkg script.

The grub2 bootloader expects the BLS linux and initrd fields values to be
set to a relative path to the root of the boot partition and the zipl tool
expects these to be an absolute path to the kernel and initramfs images.
So the grubby wrapper was removing the prefixes from the kernel and initrd
paths before doing any comparision with the BLS fields. But this shouldn't
be done if the /boot directory isn't a mount point.

The BLS files name convention used is ${MACHINE_ID}-${KERNEL_VERSION}.conf
but this means that there can only be a single entry for a given kernel.
Allow the grubby wrapper to add many entries for the same kernel image,
since the old grubby tool was able to do that. To differentiate from the
original BLS entry and to specify that it's a customized entry, add a
[[:digit:]]~custom suffix after the kernel version number.
This will also sort the custom entries before the original entry, that's
also what the old grubby tool did.

The script uses sed to modify the options field in the BLS entries, but it
is using a ',' character as the sed delimiter. It's total valid to have a
kernel command line parameter that contains that character, for example:
$ grubby --add-kernel=/boot/vmlinuz --args="console=ttyS0,115200n81" \
--initrd=/boot/initrd.img --make-default --title=install
sed: -e expression #1, char 42: unknown option to `s'

When booting an ppc64 machine on bare-metal (PowerNV) the OPAL firmware
interface is used. The firmware contains the Petitboot boot-loader that
can be used to parse the BootLoaderSpec (BLS) snippets in a BLS setup.
But machines could have an older version of Petitboot that doesn't have
BLS support, so on ppc64 machines can't be assumed that just modifying
the BLS files is enough for those changes to be reflected in the boot
menu. Instead, grub2-mkconfig is executed so the BLS can be parsed and
produce a grub config file that can be used by any Petitboot version.

So what's happened here is this:
- we planned on not having the grubby binary in this package at all
anymore
- when we did test builds like that, find-debuginfo.sh broke
- since it was completely inconsequential, we disabled building
debuginfo
- then we re-thought the package layout, and decided to build that
binary anyway, but forgot to turn debuginfo back on
- also we build the binary as -fPIE, which file(1) says is a "shared
object"
- brp-strip does not act on shared objects, so it didn't strip
As a result, rpmdiff noticed our binary was not stripped.
This patch re-enables debuginfo, which will cause our binary to get
stripped, as well as to have the correct debuginfo packages in the
output.
