Subject: [PATCH] Make it possible to subtract conditions from debug=
This makes it so you can do set debug to "all,-scripting,-lexer" and get the
obvious outcome. Any negation present will take preference over that
conditional, so "all,-scripting,scripting" is the same thing as
"all,-scripting".

Subject: [PATCH] Export all variables from the initial context when creating a
submenu
When a submenu is created, only the exported variables are copied to the
new menu context. But we want the variables to be global, so export lets
export all variables to the new created submenu.
Also, don't unset the default variable when a new submenu is created.

Subject: [PATCH] blscfg: store the BLS entries in a sorted linked list
The parsed BLS entries are stored in an array, that it's sorted
using the quick sort algorithm before populating the boot menu.
This works on the assumption that all BLS entries are parsed at
the same time and that are displayed just after being retrieved.
But the support could be made more flexible, and have different
commands to load and display the entries. Keeping the BLS in a
sorted link simplify the code considerably, while not making it
much less efficient.
While being there, mark entries that have been used to populate
the boot menu so multiple calls to the blscfg command don't add
duplicated entries.

Subject: [PATCH] blscfg: add more options to blscfg command to make it more
flexible
Currently the blscfg command is not flexible, it just loads all the BLS
entries from a predefined path and populate the menu entries at the same
time. But a user might want more control over what BLS snippets are used
to populate the entries and in which order.
So lets make the BLS support more flexible by allowing to blscfg command
to populate only the default entry, the non-default entries or choose a
custom path to a BLS snippet or a BLS directory to load the entries from.
The blscfg command now supports the following arguments:
blscfg default
blscfg non-default
blscfg (hd0,gpt2)/boot/loader/entries/
blscfg (hd0,gpt2)/boot/loader/entries/custom_entry.conf

Subject: [PATCH] blscfg: add support for prepend early initrds to the BLS
entries
There are cases where is needed one or more initramfs besides the one that
is defined in the BLS entry. For example, a user may want to add an early
initramfs to override some ACPI tables, load CPU microcode, firmware, etc.
Add support to preprend initrds if they are defined as an early_initrd var
in grubenv. Also honor GRUB_EARLY_INITRD_LINUX_CUSTOM in /etc/default/grub
and use that value to set the early_initrd var when running grub2-mkconfig.

Subject: [PATCH] Fix the looking up grub.cfg-XXX while tftp booting.
Currently, grub doesn't look up grub.cfg-UUID, grub.cfg-MAC and grub.cfg-IP
while the boot is from tftp. That is because the uuid size is got by
grub_snprintf(, 0, ,), but the grub_snprintf() always returns 0,
so grub judges there's no available uuid in the client and give up
the looking up grub.cfg-XXX.
This issue can be fixed by changing grub_snprintf(, 0, ,) behaivior
to like as snprintf() from glibc, however, somewhere may expect
such argument as the error, so it's risky.
Let's use sizeof() and grub_strlen() to calculate the uuid size
instead of grub_snprintf().

Subject: [PATCH] Try to set -fPIE and friends on libgnu.a
In order to make sure UTIL_CFLAGS and UTIL_LDFLAGS can correctly get
-Wl,-z,relro,-z,now , we need everything going in them to be built with at
least -fPIC (and preferably -fPIE) wherever we can, or else we get relocations
in some component object that can't be used with the link type that's being
used for the final ELF object.
So this makes sure libgnu.a gets built with HOST_CFLAGS and HOST_LDFLAGS,
which are what is later used to define UTIL_CFLAGS and UTIL_LDFLAGS, and
includes -fPIE.
Fixes an rpmdiff check.
