Thanks for updating this! A few other hacks that may make sense to add:

• #7305: The generated install_templates.sh file uses yum, which now needs to be installed manually in dom0.
• #7360: Github has deprecated cloning via git:// protocol, breaking some qubes-builder submodules. Based on the issue it seems this is already fixed but the fix is not yet in use by qubes-builder. A suggested solution:

git config --global url."https://github.com/".insteadOf git://github.com/

Happy to add these myself, or maybe they're temporary enough that they're not worth putting in.

Thanks.

* [#7305](https://github.com/QubesOS/qubes-issues/issues/7305): The generated `install_templates.sh` file uses `yum`, which now needs to be installed manually in dom0.

Well, yesterday, when I built the ArchLinux minimal template, qubes-builder didn't generate the install_templates.sh script. I don't know why, I will search.. So I documented in this PR a solution without this script (so with qvm-run --pass-io and dnf install).

* [#7360](https://github.com/QubesOS/qubes-issues/issues/7360): Github has deprecated cloning via `git://` protocol, breaking some qubes-builder submodules. 

I didn't see this problem, so I just checked the make get-sources command, and it seems solved (https protocol used) :

[user@builder qubes-builder]$ make get-sources

In general, you could add these temporary problems in the Known issues or Use cases sections. Check again the two above issues, and if not solved for you, then please contribute with a Pull Request, you are welcome.
