[syslinux] LUA scripting in syslinux

[Dag Wieers]

Hi,

Can we for syslinux 4.05 look to improve the LUA scripting functionality ? 
Functionality we are looking for is:

   - accessing filesystem (ext2, fat)
     - alternatively, access network services (tftp, ftp, http)

   - creating menu's from LUA
     - alternatively, generating and reloading syslinux.cfg

The use-case would be to create a lua-script that, on boot, can scan eg. a 
USB-stick for its content and based on that provide a syslinux menu. For 
the Open Source ReaR project (a disaster-recovery product) we would like 
to use syslinux so that the product can store more than one recovery image 
(multiple systems, multiple timestamps) to the USB stick and on boot the 
syslinux LUA script will generate a menu on the fly to recover a system 
using one of these images.

Something similar could be possible when the images are in fact stored on 
the network (TFTP, FTP, HTTP/DAV ?) instead. An image is typically between 
25MB and 50MB depending on the backup scenario. This would enable an 
automatic network disaster recovery service.

Another use-case is to have a LUA script that scans media for certain 
standardizes directory-layout, eg. rescue images (rip, systemrescuecd),
firmware, distro installers, ...) and based on the existence shows them in 
a menu. Such a standardized layout makes it possible for people to 
simply copy a directory on a stick to have it added to the framework.

Kind regards,
