thanks a lot for your interested in tackling this project.
Writing to the end of the first block would work for 4k or larger block
sizes filesystems, but it's not a very clean solution.
Id had a quick brainstorm with Dave and we came up with the following
- create an extended attribute on the root filesystem that is larger
than than the filesystem block size (typically 4k), and store the
syslink payload in it.
- for the first prototype get its block number using the GETBMAPX
ioctl, and use it.
once that prototype works we can talk about a good interface for you.
We could precreate the attribute at mkfs time at a fixed block number
so that syslinux can hardcode it, or we could discuss any other kind
of interface that helps you.
