Created attachment 531830 [details]
error

Description of problem: I'm trying to build a system using a kickstart file. I use the %pre section to create a file then %include it in the kickstart file later. Not matter what I write to a file I get the attached anaconda error.

I don't get any errors if I don't write to a file in %pre



How reproducible:
Use this kickstart that writes to a/tmp/include-parts
