Can someone address the boot once option. Is it to hard for syslinux to write a flag file to file system or the blank space after the mbr? .conf bootonce Lable /boot/flagfile or .conf bootonce Lable1 /boot/flagfileLable1 bootonce Lable2 /boot/flagFileLable2 bootonce Lable2 /boot/flagFileLable2 skip the default option if the flag file is 0 size.

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.

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
