Is there a way to force rustup-init to download gz instead of xz from the server?
--help indicates not, but I wanted to make sure
Edit:
Alternatively, can I disable hash/signature checking?
Edit 2:
Maybe a bit more background will help.
I'm trying to setup a rustup server within an internal network at my workplace. (Completely cut off from the internet)
I have reserved "static.rust-lang.org" and set up a self-signed SSL certificate for it, and that part's all good.
On the server, at the right location, I put a partial mirror of static.rust-lang.org, with only gz files mirrored (a personal fuck-up).
I also have a copy of rustup 1.6.0.
When I run it, it complains not finding the xz files. I can repack the gz as xz, but everything is signed using PGP (or so it seems), so that would be a wasted effort.
