I am attaching a demo script that uses two 20M sized swap-based md(4) devic= es, formats them with newfs -U and sets up some corner cases with symlinks=20 ### The error in question is, for dump/restore on 13.0: restore: warning: cannot create hard link ./usr/local/sbin/hardlink-to-abssymlink->./usr/local/sbin/abssymlink: No su= ch file or directory mtree verification: sbin/file:=20 link count (1, 2) usr/local/sbin/abssymlink:=20 link count (2, 1) usr/local/sbin/relsymlink:=20 link count (2, 1) usr/local/sbin/hardlink-to-relsymlink:=20 type (link, file) ./usr/local/sbin/hardlink-to-abssymlink missing and consequential differences shown with mtree. ### The error in question is, for tar (libarchive) on 13.0: ./usr/local/sbin/hardlink-to-abssymlink: Hard-link target './usr/local/sbin/abssymlink' does not exist. ./usr/local/sbin/hardlink-to-relsymlink: Hard-link target './usr/local/sbin/relsymlink' does not exist. mtree verification: .: modification time (Fri Aug 13 19:12:46 2021, Fri Aug 13 19:12:47 20= 21) ./usr/local/sbin/abssymlink missing ./usr/local/sbin/hardlink-to-abssymlink missing ./usr/local/sbin/hardlink-to-relsymlink missing ./usr/local/sbin/relsymlink missing ### gtar from the gtar-1.34 (archivers/gtar) succeeds!
