I'd like to be able to save a boolean value across reboots. I believe that being able to store to the auxiliary data vector would satisfy this need, but I'm using syslinux and that doesn't seem to be implemented. While I'm currently using a Lua script, I'm not tied to it, so if there's a way to read and write any persistent filesystem or disk, I'd be happy to switch.

I think the best would be adding Lua bindings for syslinux_getadv(), syslinux_setadv(), syslinux_adv_write(), syslinux_adv_size() and the BOOTONCE and MENUSAVE tags. And define some policy for allocating new tags... which is the hard part. > Reading through the source code, it seems like most filesystem > operations are read-only Yes, the filesystem driv...

This is a small set of patches for elflink branch based on feng's elflink branch. hpa, It seems that I can't log on terminus by ssh at home. So I can't push these patches on my git tree.
