The installer script tries to elevate privileges using sudo. On systems that run doas, the installation script fails. I used the specified install command on the website: curl -sSf -L https://install.lix.systems/lix | sh -s -- install. Would be great to have the script also try doas if sudo fails.

I ran it on Gentoo.

This isn't actually an issue with the script (or at least, the one on main); installer itself uses sudo, in one place:

let sudo_cstring = CString::new("sudo").wrap_err("Making C string of `sudo`")?;

This makes for a very easy fix: just check if sudo is in PATH, and check for doas if it's not.

Does modern Debian installation come with sudo, actually? When I tried it years ago, it only had su; that might also be something to check for.
