From: Paul Emmerich <p.emmerich at first-colo.net> Hi, the new API for initramfs and files in master lacked the ability to build initramfs objects from files loaded via HTTP/TFTP in Lua. The documentation indicated that it should be possible (and I believe I did that in an older version). I implemented a few new functions to handle files/initramfs objects better. Changes: * NEW:

Hi, This series targets automatic boot menu generation, but most of it is the Lua upgrade, because I got tired reading deprecated API docs. It's mostly a straightforward forward port of the earlier Syslinux specific changes to Lua 5.1, except that: * I chose the add a stub getenv() implementation to the COM32 API instead of #ifdefing out all the references in Lua, and * I kept oslib
