wget now provides a wget-udeb, linked against libssl-udeb, to support https URLs. What's the next step needed for d-i preseeding to support https? I'm interested in helping to make sure this goes in prior to the next stable release.
If possible, I'd also like to see preseed pass an extra HTTP header or custom User-Agent (e.g. User-Agent: d-i preseed Debian/$debian-version), which would make it possible for the server on the other end to detect preseeding and the version of Debian, and serve up an appropriate preseed file for that target version. That would make it easier to just point to "example.org" rather than "example.org/preseed/stable" (or some short equivalent), and the server on example.org could then include some smart logic to serve the appropriate file. Finally, would it make sense to add a new command-line option, to make it shorter to preseed an https URL without having to type the full scheme? For instance, instead of "auto url=https://example.org/";, perhaps just "auto s=example.org"? - Josh Triplett
