Backing up real-world file names and lengths doesn't work with ustar format - which pax(1) uses and also tar(1) by default. I'd prefer using pax(1) because of it's cli usage – personal taste… But in practice, I'm forced to use tar(1), overriding tar's default format with the "--format pax" (or --posix) option, for almost any archive/backup job (where zfs send isn't feasible). Since tar(1) does support the POSIX pax format, it's not a big issue, but weird using tar for pax and pax for tar ;-) I'd love pax(1) beeing libarchive(3)ed. Has anyone ever thought about? Unfortunately I'm lacking skills and time :-( Thanks, -harry
