If you provide some problematic files I’m sure they’ll be willing to help. Hello David, thanks for your hint. I'm using libarchive(3)'s pax-support by tar(1) already, so I'm not sure if these are the ones interested to make pax(1) use libarchive(3). If I remember correctly I haven't had problems restoring files with NFSv4 ACLs, but that's not the major problem anyway. My real-world problem is that the pax(1) tool can't restore from/backup to pax-format files. All supported formats by pax(1) have unpractical path/filename length limits. I'm aware of cpio(1) and tar(1)s transition to libarchive several years ago. Unfortunetly pax(1) was overseen :-( Would be wonderful if someone could catch up pax(1)'s libarchive(3) transition, but I guess the libarchive developers aren't interested or have very much spare resources… Thanks, -Harry
