_ Please don't forget about updating the gnu-efi submodule to the 
newest commit (not now but rather just before a relevant pre-release). 
This also would need testing.

_ IMHO, it would be very desirable to update (some of the) code that is 
included in Syslinux, _while testing for regressions_ (especially if 
some feature has been dropped from those), e.g. jpeg, libpng, gfxboot 
(from github), zlib, lzo, gdb... If not to a new major version of 
those, at least they should be updated to the latest respective minor 
versions. IMHO, this is the only way to really narrow down reported 
problems (e.g. jpg/png background, or certain kernels not loading as 
expected...).

_ IMHO, not having some "gptmbr.bin" supporting XFS would be kind of 
embarrassing. Imagine including in the changelog something about the 
support for the newest XFS version but with a caveat "only in MBR, not 
GPT".

If the current mbr/*.bin cannot be patched, then perhaps adding a new, 
specific one supporting XFS could be an alternative. Of course, 
patching mbr/*.bin would be better than adding a new specific one.

_ Patching chain.c32 so to correctly support the current Reactos 
loader. The current code in chain.c32 fails because the default values 
for Reactos are outdated (and no longer working, for several years 
now).

_ Additionally, the "keeppxe" argument has been broken since v.5+, and 
still is as of v6.03. keeppxe is also required for netbooting Reactos.


This is only a partial list, and these are not necessarily the most 
important items to my own needs / wishes.

TIA,
Ady.
