That's cool! If possible, could you please share a tarball of it?
May be in the future. There is a lot of broken stuff at the moment.
My current stage4 is based on an old kernel 2.6.23 and a 2007-8 stage4 with some modern updates/patches/workarounds that I have made year after years, plus some personal applications written by me. For me it's "ok" as I have been using daily it since 2007 and I can coexist with all the problems it has, but with my recent needs I myself have reached the point where there are so many broken unstable things that the new plan for the 2021 is to prepare a full set of recipes for Catalyst and launch it to build a completely new stage4. But first I have to find a valid candidate for the kernel of which I I have to have to the full trust about mobility because I seriously need to use my PDA on traveling.
