   - symmetric hlid (all hardlinks pointing to same inode have same hlid)
   - all archived hardlinked regular files have a chunks list
-- borg init --other-repo=OTHER_REPO: reuse key material from OTHER_REPO, #6554.
+- borg rcreate --other-repo=OTHER_REPO: reuse key material from OTHER_REPO, #6554.

   stay the same, the deduplication will also work between past and future backups.
