was recently asked if i could teach a course to prepare some folks
to write the RHCSA (red hat certified sys admin) exam, so i was
reviewing the official list of what they would need to know here:

https://www.redhat.com/en/services/training/ex200-red-hat-certified-system-administrator-rhcsa-exam

and i was intrigued by this line:

"Archive, compress, unpack, and uncompress files using tar, star, gzip, and 
bzip2"

  "star"? it's been a while since i saw a reference to that -- the man
page is here:

  https://linux.die.net/man/1/star

and one of the selling points of star is its ability to archive ACL
information. but there are certainly other ways to archive ACL
information.

  regular "tar" these days seems to be ACL-aware:

    Extended file attributes
       --acls Enable POSIX ACLs support.

  "rsync" also handles ACLs and extended attributes:

       -A, --acls                  preserve ACLs (implies -p)
       -X, --xattrs                preserve extended attributes

  and one of the popular recommendations is to save ACL info
separately from archiving since one expects it to change much less
frequently than file content, so one can use getfacl and setfacl:

  $ getfacl -R . > permissions.facl
  $ setfacl --restore=permissions.facl

given all of this, does anyone here use "star" for regular archiving?
it seems that star is superfluous given other solutions, but i'm
willing to be corrected.
