[systemd-devel] implementation status of http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec/ ?

[Colin Walters]

What's the implementation status of
http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec/ ?

For example, do any patches exist for grub or syslinux to read
from /boot/loader (either at runtime or to generate a bootloader-native
config file statically?)

I'm aware gummiboot does (and its wiki page should probably crosslink
with the above).  But any others?
