Any help would be appreciated. I'll post to >comp.unix.misc if anyone expresses interest in seeing the results. Of those mentioned, All but IBM, SCO, and Apple can use FFS. They are not mount time interchangable because of byte order, disklabel, volume info struct, and structure alignment issues, which are not considered to be protability issues when moving FFS to another system (it may be to your advantage to have your system mount someone else's disks, but it's not to your advantage to let them mount yours, and given conversion overhead, byte order conversion will make your benchmarks look bad comparatively when mounting a foreign disk). Please post your result back to this group (comp.unix.bsd) as well, since FFS had BSD origins in any case.
