@cinerea0 Will it work with `.pam`? I've checked the Arch [PKGBUILD](https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=greetd) and it looks like they are using it without the extension:
```
  install -Dm644 "$srcdir/greetd.pam" \
    "$pkgdir/etc/pam.d/greetd"
```
For me renaming it to `greetd` did not create any problems. I'm not using keyring though :)
