Hello LemonParty1
It seems we are doing the same thing but for different reasons. Anyway, I see you renamed the firewall to GNS, but taking a closer look to your log file, it seems you forgot to rename one of the build.conf lines to GNS, cause it is still showing "MyFirewall" as the PIBA-NL wiki is showing.
Not sure if you already figured it out, but if you don't, try it again renaming all fields to "GNS" as you did to the other fields/lines.
I could generate a brand new ISO file with a different name. It took me a week to understand everything, but it's now much more clear to me.
I didn't try to generate a RELEASE ISO file yet, just a DEVELOPMENT. Let me know if you could finally finish your compilation.
Meybe we can exchange good information.
Regards
Fabricio.
