Why Lua support was removed

[Tianjia Zhang]

Hi everyone,

I want to use lua to do some logic on grub, which needs to be embedded 
in the lua interpreter. I found that grub supports lua as early as 2009, 
and only a few months later, the lua was removed. I checked the 
Changelog and git log, the reason for removal was not found, I want to 
know why the support for lua was removed.

Judging from the current situation, if grub wants to support a scripting 
language, lua is undoubtedly the most suitable and completely feasible. 
Is it acceptable to support lua in grub now? If possible, I will 
consider doing this.

Best regards,
Tianjia
