I have used TinyCore, on several computers for years. I really like it.
I dedided to try dCore because I hoped to be able to download and try programs contained in the .deb repositories that are not available in the tinycore repositories.
This was a test, try and download and use the latest firefox from a repository that is not in the base repository that stock dcore uses. So the question is...how do you add additional repositories and access them?
I have tried to add locations to .../opt/debextra/...using ppa-add...and also manually adding a file, all without sucess.
A suggestion, .....include a ../opt/debextra/ with a set of files for repositories that are know to work...which the user could manually edit as necessary adding or deleting repositories he did or did not want to use. Seeing working examples would really aid in learning how to use additional repositories.
Using dCore to access lots of additional software would seem to it's strength, and as such more documentation and examples on how to do this would be a real plus.
