If you recreate it natively using file -C, it also works. A-HA! Are all the file(1) problems you've mentioned only occurring for cross-arch builds? If this is the case, we can disable building magic.mgc if TARGET_ARCH != MACHINE_ARCH. > AFAIK, the underlying reason hasn't been tracked down. To date we've never guaranteed that a cross-arch built world is usable. We only officially support cross-arch compiles for compile testing. There are other things in the tree that aren't size & endian-clean that prevent usable cross-arch release builds. -- -- David (obrien@FreeBSD.org)
