That would be the only advantage. I don't use ddb, since it's too restrictive (no access to sources), so it wouldn't make any difference for me. > In any case, I like the idea of having ONE kernel and having the > loader not load the debugging gunk into memory. Yes, I think that's the superior solution as well. It would mean that you would have to make root file systems 20 MB larger by default. There are other options here. Since it's a separate issue, I'll send out a separate message: how about having a boot partition with just the kernels and enough information to locate the root file system?
