CentOS 6 lacks a realpath binary on the base install, which makes all iotests runs fail since the 2.11 release:
001 - output mismatch (see 001.out.bad) ./check: line 815: realpath: command not found diff: missing operand after `/home/dummy/qemu/tests/qemu-iotests/001.out' diff: Try `diff --help' for more information. Many of the uses of 'realpath' in the check script were being used on the output of 'type -p' - but that is already an absolute file name. While a canonical name can often be shorter (realpath gets rid of /../), it can also be longer (due to symlink expansion); and we really don't care if the name is canonical, merely that it was an executable file with an absolute path. These were broken in commit cceaf1db. The remaining use of realpath was to convert a possibly relative filename into an absolute one before calling diff to make it easier to copy-and-paste the filename for moving the .bad file into place as the new reference file even when running iotests out-of-tree (see commit 93e53fb6), but $PWD can achieve the same purpose.
