If you look at the way the rustup-init.sh script is written it's safe to be used with this "anti pattern". I see your objection though but unfortunately this ship has sailed, you might as well complain about websites that don't work without Javascript...

The advantage of this method is that it will work on any linux distro (and even BSD, Darwin and mingw) and you'll get the latest stable version. I don't see the advantage of using potentially outdated OS packages for installing a compiler, it's not like it's a dependency for other packages.

It also makes it easy to manage the various components of the toolchain, for instance if you later want to crosscompile for an other target, use the nightly version etc...

That makes no sense. If one curls to bash obviously they can't "look at the way the rustup-init.sh script is written".

The ship hasn't sailed and neither has the sites without JS one. You have made a decision to favor covenience instead of security and you're trying to make it look like it's the normal state of affairs.

Rust can be installed by downloading the appropriate package and checking it with gpg.

Recommending curling stuff to bash is ridiculous and makes a mockery of the idea of safety.

You're planning on downloading binaries and gpg keys from that site anyways. Either you trust it, in which case you might as well curl | bash, or you don't, in which case you shouldn't be running that script no matter how carefully you inspect it.

And of course you can inspect the bash script (not that it does you any good), curl > file; bash file. It's just that most people don't so that's not what is recommended .

No, you're completely wrong. The key is available in multiple places and has been available for a while, so there is some verification that can be done.

The binary will be checked by gpg, it shouldn't matter where it's from.

Finally, if the recommmendation is to run curl foo | sh, the bash script can literally not be inspected.

Just separate the steps? Curl to a file, inspect it, and then execute it? I don't see the problem. Most users just don't care because it's official anyways.
