Hi Chen, 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 idea: - 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. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
