Thank you, curaga. Finally, a relevant response. You'd think if someone has stated that they had managed to do a microcore installation using directions found at those links, someone would not be trying to tell them it lacks a GUI. Of course I'm assuming that the responder actually read my posts and even gave the matter at least a little thought--likely a faulty assumption.
I've just gone ahead and adapted those directions to my needs changing, where necessary, some file names (e.g., the kernel is named vmlinuz on the CorePlus CD, while the compressed image is core.gz). I've now gone ahead and done a test install on real hardware (was using qemu previously) and it seems to be working as I'd hoped.
I may try your suggestion as well to see whether it will offer any advantages. E.g., maybe the persistence options will be better configured. Anyway, thanks for your input.
