UX: cargo build rage builds each time

[histrio]

What were you trying to do

Install rage via cargo twice.

What happened

The build has happened. The package is recompiling even if there are no new changes.

If you're referring to cargo install rage, I believe this is caused by rust-lang/cargo#8703. The rage package includes the rage-mount binary which is built when the mount feature flag is provided. There's unfortunately nothing I can do about this while retaining the ability for cargo install rage to optionally provide rage-mount.
