rustup fails if sudo is not available

[pwaller]

I'm running in a minimal docker container, as root.

Rustup fails with sudo: command not found, even though I'm root and sudo is not necessary.

I think running as root should imply --disable-sudo. Running into the same issue.

Also when failing, it does not save data (as in --save), so further re-run with --disable-sudo re-downloads.

I did manage to install rust most recently when I tried so I must not have hit this problem. It's possible I installed via a binary image though.

I'm not interested in following this issue up, so I'm closing it. Please open a new issue if you want to keep tracking this.
