The custom disk-usage-collector shell script + minutely timer is replaced
by prometheus-zfs-exporter (pdf/zfs_exporter, packaged in nixpkgs as
services.prometheus.exporters.zfs). The exporter provides pool capacity
metrics (allocated/free/size) natively.
Partition metrics (/boot, /persistent, /nix) now use node_exporter's
built-in filesystem collector (node_filesystem_*_bytes) which already
runs and collects these metrics.
Also fixes a latent race condition in serviceMountWithZpool: the -mounts
service now orders after zfs-mount.service (which runs 'zfs mount -a'),
not just after pool import. Without this, the mount check could run
before datasets are actually mounted.
Add trilium-server on port 8787 behind Caddy reverse proxy at
notes.sigkill.computer. Data stored on ZFS tank pool with
serviceMountWithZpool for mount ordering.
- coturn: switch static-auth-secret to static-auth-secret-file
- matrix: switch registration_token and turn_secret to file-based
- murmur: switch password to environmentFile with agenix
- p2pool: move public wallet address to service-configs.nix
