+Subject: [PATCH] blscfg: Always look for BLS snippets in the root device
+
+The blscfg command trying to load the BLS snippets from different devices
+is a left over from when these where located in the ESP in the EFI case.
+
+But now that are always located in the /boot directory, the BLS snippets
+have to be loaded from the root device just like the other files that are
+in the /boot directory (kernel and initrd images).
+
+This only worked for legacy BIOS because the boot and root variables were
+set to the same value. But doesn't work when trying to use a common GRUB
+config file that could be shared between an EFI and legacy BIOS install.
+
+That kind of configuration is needed for example on hybrid images that are
+booted using either EFI or legacy BIOS firmwares.

+Subject: [PATCH] blscfg: Don't hardcode an env var as fallback for the BLS
+ options field
+
+If the BLS fragments don't have an options field or if this was set to an
+environment variable that was not defined in the grubenv file, the blscfg
+module searches for a default_kernelopts variable that is defined in the
+grub.cfg file.
+
+But the blscfg module shouldn't hardcode fallbacks variables and instead
+this logic should be handled in the GRUB config file itself.
+
+Also, add a comment explaining where the kernelopts variable is supposed
+to be defined and what is the process for the user to change its value.

+Subject: [PATCH] tftp: roll over block counter to prevent timeouts with data
+ packets
+
+The block number is a 16-bit counter which only allows to fetch
+files no bigger than 65535 * blksize. To avoid this limit, the
+counter is rolled over. This behavior isn't defined in RFC 1350
+but is handled by many TFTP servers and it's what GRUB was doing
+before implicitly due an overflow.
+
+Fixing that bug led to TFTP timeouts, since GRUB wasn't acking
+data packets anymore for files with size bigger than the maximum
+mentioned above. Restore the old behavior to prevent this issue.
