@Rich: The Ibiblio project was likely signed up for quite some time ago (very likely they're found in mirrors.tcz) and it's one we found to be fast and frequently updated with TCL and a number of other useful repositories so we tend to lean on them instead of repo.tinycore and other master resources, but yes, when we add/remove something on our repo.tinycorelinux.net server, they'll reflect those changes usually within 24 hours or so, many times much less than that it seemed.
@Curaga @Paul_123: We just found something odd and passed it along; I have not tested 15x as 14x was our focus group for a server test, being seen a little more as "tried and tested." If memory serves, 13.x only has KERNEL source; busybox and toolchain don't exist on repo - how far back I don't know; that was Béla's wheel house back then
if I'm not mistaken and may just not be posted or may be elsewhere.
@CNK: I'm not sure what you mean by this. Slow servers?
Yes, very slow both for uploading
and downloading. Fear not, though... a functional method will present itself in the end!
Oracle Cloud's 200GB of "Block Volume Storage" does not sound, from what I just read, as though it would be useful for drop-in functionality (ie: could be made to work with apps or tce-load) BUT you also note VPS and SystemD so maybe there's a web based functionality I didn't see in their Always Free tier.
