Please include the one extra character that turns on `--fail` for curl, lest `HTTP/2 500\r\ncontent-type: text/html` sent right into a shell ruin some user's day

    curl -fsL run.linkerd.io/install | sh

and, while I can appreciate how slick it may look, in a post about mTLS including the protocol can save someone the coffee shop/hotel intercepting the request and violating the Authenticity tenant, to say nothing of, again, sending html into shell

    curl -fsL https://run.linkerd.io/install | sh

I didn't bother to read the relevant scripts, but it's very, very likely they contain bash-isms, in which case those other 2 characters can also lead to better outcomes:

    curl -fsL https://run.linkerd.io/install | bash
