[syslinux] fwrite?

[Bryan.James.Krone-EXT at jci.com]

Is the auxilliary data vector only accessible by Extlinux or does it also 
work with Syslinux? I'm booting from a vfat partition.

There is --once, but it sounds like you want it to have a counter.  The
way to store persistent data in Syslinux is the ADV (auxilliary data
vector) which has its own API.

Adding a counter to the --once mechanism would be fairly easy.

                 -hpa
