[Bug 456405] Re: pax lack of support for "pax" format fails LSB

[a7x]

There are two separate but related issues here:
  1.  the pax utility doesn't support the pax format (a LSB conformance bug in pax)
  2.  the pax utility isn't installed by default (a LSB conformance bug in ubuntu-meta)
This bug report seems to be about the first issue, so I'm moving this to pax.  A separate bug should be opened for the second issue.

** Package changed: ubuntu-meta (Ubuntu) => pax (Ubuntu)

Title:
  pax lack of support for "pax" format fails LSB

Status in “pax” package in Ubuntu:
  New

Bug description:
  The SUS/POSIX standard tool pax is required for LSB 3.2 compliance.  The
  version of this tool on Linux (all systems I've tested) provide ustar format
  but not 'pax" format.  "pax" format is required by LSB; it is needed to backup
  ACLs and extended attributes including SE Linux labels.

  libarchive does support pax format.  It should be easy to create a front-end
  for pax that uses libarchive (which comes with bsdcpio front-end, but not in
  the Fedora 10 package).  SUSv3 and SYSv4 (and POSIX all required this format to
  be supported, and LSB 3.2 does as well.)  Not supporting it means no standard
  tool can make archives with EAs; more importantly it means Fedora (and
  presumably Red Hat) is not compliant with the LSB.

  How reproducible:
  Always

  Steps to Reproduce:
  try "pax -x pax" ...

  Actual results:
  pax: Unknown -x format: pax

  Expected results:
  should work.

  Additional:

  I originally reported this against Fedora.  The maintainer, ovasik at redhat.com, confirms no distro
  supports this and has written a patch.  (See Fedora bug #503860.)  But libarchive supports this
  so I think it should be fairly easy to lift that code, or just invoke that .so from pax?
