Subject: [PATCH] Changed "realpath" in the scripts (added from a pull request
 merge earlier today) to "readlink -f", because "realpath" does not exist on
 some systems (e.g., CentOS).  "readlink" seems to be more universally
 available.  Noticed that the ext2spice and ext2sim scripts use /bin/sh
 instead of /bin/bash, which would cause problems with some systems where sh
 != bash.
