The first time it ran ok. But I had no way to do it again. Spent hours trying to get the Mac partitioner to just clear out the space so I could re-run the installer. No dice.
In the end I did a factory reset of the whole macbook and then I could reinstall Asahi.
Curiously I found it a breeze since it didn't require digging out a flashable boot medium and pointing your BIOS to it. Calling a script from your normal desktop environment and having it automatically boot into the installer was really nice.

What's this about? The script takes care of resizing the macOS partitions and creating new ones for Linux.
