+## [bug #44238] Add support for menu.c32 and vesamenu.c32 in lib/syslinux_parse
+## [bug #44239] Behavior of syslinux_parse differs from SYSLINUX for initrd= option
+## These make vesamenu.c32 work (translation: Debian/Tails ISOLINUX) but they are
+## buggy at the moment; Trisquel ISOLINUX parsing fails with these patches, for instance:
+## "error: syntax error.", "error: Incorrect command."
+## The mailing list contains updated versions of the patches mentioned below
+## Work with Lunar^ on IRC on finishing the patch so that it fixes the issue
+## while not causing other regressions. Wait until this is merged in GRUB(upstream).
