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 drivers in Syslinux are read-only. -- Feri

From: Sylvain Gault <sylvain.gault at gmail.com> Hello there, I propose 2 patches that fix two possible stack overflows either when running a COM32 module or when loading a new config file. I didn't find a better way to do this than to use the infamous setjmp/longjmp functions to restore the stack to a previous state. This makes the logic a bit more complex, but the behavior is not

From: Matt Fleming <matt.fleming at intel.com> Here are the patches that I've got queued up based on the very helpful feedback I received from people testing Syslinux 5.00-pre9. Unless anyone has any concerns these will make it into Syslinux 5.00-pre10. Matt Fleming (9): pxe: Don't call open_config() from the pxe core ldlinux: Print a warning if no config file is found

From: Matt Fleming <matt.fleming at intel.com> Since we can't use __intcall() for EFI, and since we can now have the ELF module code resolve all our symbols at runtime, we should delete as many references to __intcall() as possible and just access the symbols directly. The most interesting patch is the support for weak symbols. We need to be able to reference derivative-specific

From: Matt Fleming <matt.fleming at linux.intel.com> This series fixes some bugs and switches the elflink branch to be entirely ELF modules. It applies on top of, http://syslinux.zytor.com/archives/2011-April/016369.html The deletions in the diff stat below are mainly from deleting com32/elflink/modules (finally!). Now there should be no duplicate code because we don't need COM32 and
