** Description changed:

- A recent merge that added a mkfs.ext4 tests has a hard coded location
- for the binary of mkfs.ext4. The result is that on centos 7, which has
- the command in a different location than Ubuntu, is a failed test:

+     
+ === Begin SRU Template ===
+ [Impact] 
+ Unit tests for cloud-init did not run successfully in a centos environment.
+ This is really just failure of the unit tests.
+ 
+ The fix was to no longer expect /sbin/mkfs.ext4 but to mock the
+ checking.
+ 
+ [Test Case]
+ Test of ubuntu package in centos is non-trivial and/or not useful.
+ The proposed test case is to just run the trunk tests at the
+ uploaded git commit in a lxc container (the environment that originally
+ found the issue).
+ 
+ $ lxc launch images:centos/7 c7
+ $ sleep 10; # let it boot
+ $ lxc exec c7 -- /bin/sh -xe <<"EOF"
+ yum install --assumeyes epel-release
+ yum install --assumeyes pyserial python-argparse python-cheetah 
python-configobj python-jinja2 python-jsonpatch python-oauthlib 
python-prettytable python-requests python-six python-pip PyYAML git file 
e2fsprogs
+ pip install contextlib2 httpretty mock nose pep8 unittest2
+ git clone https://git.launchpad.net/cloud-init
+ cd cloud-init
+ git checkout 16a7302f
+ nosetests tests/unittests
+ EOF

+ 
+ [Regression Potential]
+ No runtime regression potential.
+ Unit test only changes.
