Subject: Add -c option to specify keyd config file on command line
X-Git-Url: https://git.sommitrealweird.co.uk/onak.git/commitdiff_plain/f5037a4a370b891e14971228c1d491184c7fe8bd

Add -c option to specify keyd config file on command line

  Matches the parameter the onak binary takes and allows use of
  something other than the compiled in default config file path.
