Bug 1129104

Description of problem:
When a process listens on port 8080, katello-installer fails to succeed, logging weird tomcat6 start error.

No doc mentions that port to be free.


Version-Release number of selected component (if applicable):
(not sure, coming from Sat6 testing day)


How reproducible:
100%


Steps to Reproduce:
1. Have any process listening on port 8080
2. launch katello-installer


Actual results:

  Something went wrong! Check the log for ERROR-level output
  The full log is at /var/log/katello-installer/katello-installer.log


Expected results:
Some better error log to be provided (katello-installer.log does not have anything usable, I had to check catalina.out)

Installation doc should mention port 8080 to be free.
