This includes configuring Nix Bitcoin within my existing flake. The
intent is to run Bitcoin Core, LND, Electrs, Mempool, and Alby Hub here
instead of via Umbrel.
Note, Fulcrum was tried but kept crashing and losing state... which is
not okay with me.
This focuses on being able to build a SD card image for a Pi 3 named
raspberry and the cofig it contains. As part of making that happen, I
found that I had totally messed up hetznix02's hardware config. I fixed
this as it is where I am builiding the SD image. This work also resulted
in adding a "volume" to hetznix02 and moving `/nix` onto it.
I am having lockups like the crew of Linux Unplugged described having
with a rull real time kernel... disabling zen for now to see if that
makes them stop.
This is being done as a step before moving to the nix version of ABS.
That change would be included here too, but I ran into a bug:
```
[2024-12-02 19:53:46.433] FATAL: [Server] Unhandled rejection: [Error: EACCES: permission denied, mkdir '/metadata'] {
errno: -13,
code: 'EACCES',
syscall: 'mkdir',
path: '/metadata'
}
promise: Promise {
<rejected> [Error: EACCES: permission denied, mkdir '/metadata'] {
errno: -13,
code: 'EACCES',
syscall: 'mkdir',
path: '/metadata'
}
}
```
No idea why yet so the container lives on.
To setup the mountpoint, I ran `zfs set mountpoint=legacy
orico/audiobookshelf` and created the directory used as the mount in the
`fileSystems` section.
