Please bear with me regarding my coding I'm not a programmer,  I am also aware I have removed some of the checks etc. I will look at bring those in once I can get the config out putting fine.

depending upon what these hacks are, if they are invasive, i suggest a separate
script.

I suspect this is something to do with the commands in the commandtable calling the subs, I could be totally wrong here. (By the way I'm not looking for formatting at the moment just looking for some output)

most likely it is not matching the prompt.  see NOPIPE in rancid.conf(5)
and rancid -df, which are handy testing knobs.
