I've had cp -a fail with trying to migrate complete partitions when it
got to /dev/ special files. I don't know why it failed, but it did. cpio
worked. I guess tar versus cpio or cp also have different memory
footprints, one might have different restrictions than the other on
systems low on memory. I also had problems with cp during a filesystem
migration because I do happen to have some directories with multiple
hard links on individual files (this is on purpose as a way to have a
non-sym linked cvs tree that has a second "view" for compiling and
developing...cvs tends to dislike sym links).
