Remove them all. You can complete clean this file. You needs nothing of 
this entries.

Do you have perhaps not changed the file 
"*-|persistent-net-generator.rules|" ? The "generator" of this stuff.

The steps are:
First edit the file "*-|persistent-net-generator.rules|" and add a bypass.
Than remove all entries with "(conet)" from the file 
"*-persistent-net.rules".
Than reboot.

Or, if you wish to have fixed MAC for every time and for every user of 
your image, than add any of the MAC you have seen to the coLinux config 
file. Let start you self managed MAC with "02:ff:...". This way would 
need, if you switch the starts between command line running and "coLinux 
as service".
