Hmm ... I'm not sure, although I'm fairly happy about giving up
filesystem backup utilities (*dump) in favour of file-by-file backups if
there's a sufficient reason. It seems that the more I learn, the less
certain I am :)

Yup. 'man setfacl' for Linux or Solaris, and 'man chacl' for IRIX. I'm
not sure how widely used ACL's are, but I've used them myself in the
past. I don't know that GNU tar doesn't backup ACL's but the info page
(at a quick look) doesn't seem to mention it, so it seems unlikely.
