"TypeError: not enough arguments for format string" seen when installing a system using a kickstart

Issue

• When installing a system which has Fiber Channel disks, the following message is displayed:

  Traceback (most recent call last):
    File "/usr/lib64/python3.6/logging/__init__.py", line 994, in emit
      msg = self.format(record)
    File "/usr/lib64/python3.6/logging/__init__.py", line 840, in format
      return fmt.format(record)
    File "/usr/lib64/python3.6/logging/__init__.py", line 577, in format
      record.message = record.getMessage()
    File "/usr/lib64/python3.6/logging/__init__.py", line 338, in getMessage
      msg = msg % self.args
    File "/usr/lib/python3.6/site-packages/blivet/devicelibs/edd.py", line 268, in __repr__
      return "<EddEntry%s>" % (self._fmt(' ', ''),)
    File "/usr/lib/python3.6/site-packages/blivet/devicelibs/edd.py", line 232, in _fmt
      return s % d
  TypeError: not enough arguments for format string
  

• The installation continues anyway
