Dear Maintainer,

Please add functionality to 7z to preserve hard links when extracting
isos.  Thanks, Jayen.

   * What led up to the situation?
Unzipped fedora isos.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
Effective: loopback mounting the iso and copying the files with rsync -H
Ineffective: 7z x boot.iso

   * What was the outcome of this action?
Files were extracted twice.

   * What outcome did you expect instead?
Hard links.

I have discovered same issue with symlinks in ISO's on Debian Stretch.

firmware-9.5.0-amd64-netinst.iso iso image is extracted without firmware
package symlinks (/firmware directory is empty). Had to migrate to bsdtar..
