Hi Eric, Right now, in the create_mymodule_config(), I allocation memory for the config struct, and set a (single) default value. As I said, I also currently have some printf's, so the msgs show up twice. Other than the msgs showing up twice, is there any harm is NOT trying to detect the 1st pass, and just doing the allocation and setting the default, twice? I think that I read somewhere that after the 1st pass, everything is unloaded, so when the 2nd pass occurs, it's basically starting from scratch anyway. Jim
