Hi Florent, > I thought PPC could work in both endian modes (31th or 63th bit > of MSR), that would mean FreeBSD/ppc could read UFS volumes > created by FreeBSD/i386 but not the opposite. > > Please tell me if I'm wrong. Little-endian mode has varying degress of support on different processor models (e.g. none on the G5). Like it or not, PowerPC == big endian. The real fix for UFS interoperability is the NetBSD approach, but that has a complexity in making sure that *all* metadata reads/writes are appropriately swapped. later, Peter.
