Asahi Linux pre-alpha installer test notes:

Run this:

    curl -L https://mrcn.st/alxsh | sh

You can run it from macOS, recoveryOS, or 1TR. It should do the right thing.
Just follow the prompts.

Prerequisites:

* A working macOS install, >= 11.4, with a machine owner user
  (i.e. go through initial setup).
* Either a blank APFS partition (>=2.5G) or free unpartitioned space
  (this won't resize macOS for you, yet.)

No guarantees that it won't eat your data, though I haven't seen it do anything
crazy so far.

This will only install m1n1, it makes no attempt to partition and install a
rootfs or anything like that. The m1n1 part is the hard part, so all testing is
appreciated.

All feedback on the experience is appreciated. If you run into a problem,
screenshots with the system/partition info as printed by the installer would be
helpful.
