# /etc/systemd/system/mnt-media.mount
#
# Installed by `scripts/media-view.sh install` — the repo copy is the source of
# truth (fleet law: never edit host state by hand).
#
# An OverlayFS merge that shows the media library as one tree while splitting
# where its bytes live: lowerdir is the RAID6 array (the source of truth, never
# written), upperdir is a directory on the NVMe that receives every write. The
# two media servers bind the result at /mnt/media, so Jellyfin's Kodi-format
# sidecars and artwork are SSD bytes — which is what makes them fast to browse
# and what keeps Plex's NFO agent off the spinners — while the media itself stays
# on the array untouched.
#
# RequiresMountsFor is load-bearing: without the array mounted, lowerdir is an
# empty directory and the view would present an empty library as truth.
