Description of problem:
When verifying bug 691417 I faced problem with spacewalk-koan after provisioning a system. I ran rhn_check -vv to apply kickstart and it failed when running find_ip(device) from /usr/share/rhn/spacewalkkoan/spacewalkkoan.py. It is caused due to  supporting only english locale of system, so on all other localized systems this will fail.

line 51:
  def find_ip(device):
      return execute("ifconfig %s | perl -lne '/inet addr:([\d.]+)/ and print
$1'" % device)[0]

  ifconfig on english system:
      inet addr:xxx.xxx.xxx.xxx
  ifconfig on german system:
      inet Adresse:xxx.xxx.xxx.xxx
  ifconfig on czech system:
      inet adr:xxx.xxx.xxx.xxx

line 48:
  def find_netmask(device):
      return execute("ifconfig %s | perl -lne '/Mask:([\d.]+)/ and print $1'" %
device)[0]

  ifconfig on english system:
      Mask:xxx.xxx.xxx.xxx
  ifconfig on german system:
      Maske:xxx.xxx.xxx.xxx
  ifconfig on czech system:
      Maska:xxx.xxx.xxx.xxx

Version-Release number of selected component (if applicable):
spacewalk-koan-0.2.7-7

How reproducible:
always (on lozalized systems)

Steps to Reproduce:
1. in RHN Satellite: Systems -> [select system] -> Provisioning -> [select kickstart] -> Advanced Configuration -> Network Connection: Use static interface [select interface] -> Schedule Kickstart and Finish
2. on client machine: rhn_check -vv to apply this kickstart
3. kickstart applying failed
  
Actual results:

initiating spacewalkkoan kickstart

    return execute("ifconfig %s | perl -lne '/inet addr:([\d.]+)/ and print $1'" % device)[0]

Expected results:
kickstart is applied
