+To list all nightlies from 2023, run:

+ghcup install ghc 9.7.20230619

+## Esoteric distros
+
+### Void Linux
+
+Since void linux can be installed with glibc and musl, it's hard to support correctly with ghcup.
+One way to make ghcup work on **Void Linux musl** is to follow the [Overriding distro detection](../guide/#overriding-distro-detection)
+section and tell it to consider Alpine bindists only. E.g.:
+
+```sh
+curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | BOOTSTRAP_HASKELL_MINIMAL=1 sh
+source ~/.ghcup/env
+ghcup config set platform-override '{ "arch": "A_64", "platform": { "contents": "Alpine", "tag": "Linux" }, "version": "3.17" }'
+ghcup install cabal --set latest
+ghcup install ghc --set latest
+ghcup install stack --set latest
+ghcup install hls --set latest
+```
