Move greetd config to data and add autologin example

[agx]

Having it in data eases finding it and people ever so often wonder how to auto log in.

There's additional copies for apline and fedora which we could get rid of if we use e.g. meson and add --vt and --greetd-user options but that could also be a follow up.

Awesome, thanks 👍

I still find the idea of wrapping our Cargo.toml in Meson kinda icky. Maybe squeekboard traumatized me and now I'm convinced I can never love again, idk.

At any rate...

What you're describing could still be achieved in a straightforward manner with some build.rs shenanigans, no? i.e at build-time you look for PHROG_GREETD_VT/etc and spit out a generated greetd.toml in $CARGO_TARGET_DIR or somesuch.

I maintain the Fedora and Alpine packaging, so if you wanted to align Debian's upstream packaging on this convention and we make sure we reuse exactly the same 🐸ified greetd.toml, I'd love that and would (well, ask the 🤖 xD) to do that build.rs thing and formalize it.

We wouldn't need to do that. They can be entirely separate or build.rs could call meson (but then passing command line options becomes harder)

and we make sure we reuse exactly the same 🐸ified greetd.toml

Issue here is that different distros use different users which is hard to change (for little gain upstream).

I think shipping a reference config that downstream can grab and potentially patch is better than having everyone guess so the whatever works best for you works for me here to get rid of the duplication. We could also detect $distro at build time and put out the right params in build.rs ?
