Description sapan.ganguly 2015-03-13 17:38:59 UTC
Description of problem:

koan doesn't support CentOS 7's version numbering, so in os_release function of /usr/lib/python2.7/site-packages/koan/utils.py, replace

      for t in tokens:
         try:
             return (make,float(t))
         except ValueError, ve:
             pass
      raise CX("failed to detect local OS version from /etc/redhat-release")

with

      for t in tokens:
         try:
             match = re.match('^\d+(?:\.\d+)?', t)
             if match:
                 return (make, float(match.group(0)))
         except ValueError, ve:
             pass
      raise CX("failed to detect local OS version from /etc/redhat-release")

Version-Release number of selected component (if applicable):

2.6.7-1.el7

How reproducible:

Everytime koan is used on EL7.

Steps to Reproduce:
1. Build an EL7 machine from Cobbler
2. Try and run koan --replace-self
3. Observe the problem with reading /etc/redhat-release

Actual results:

Error message (sorry, I didn't keep a copy).

Expected results:

After the changes to utils.py mentioned above the koan command is successful, I can then reboot the box and have it re-build.
