exec of "cargo" will not work on systems that don't have the Rust toolchain / cargo in $PATH.

crosswind/src/bin/tailscale.rs

Line 94 in 002ea08

let err = exec::Command::new("cargo").args(&argv).exec();

Running a cronjob that launches crosswind automatically on a cloudkitten and it dies in the line above:

ubuntu@cloudkitten-singapore:~$ tail -f /var/log/serval/crosswind.log 
thread 'main' panicked at 'Error: couldn't exec process: No such file or directory', src/bin/tailscale.rs:95:5
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

is there a way to more generically express this functionality?
