# configuration options (today i don't store my config in nix):
#
# - jellyfin-web can be statically configured (result/share/jellyfin-web/config.json)
#   - <https://jellyfin.org/docs/general/clients/web-config>
#   - configure server list, plugins, "menuLinks", colors
#
# - jellfyin server is configured in /var/lib/jellfin/
#   - root/default/<LibraryType>/
#     - <LibraryName>.mblink: contains the directory name where this library lives
#     - options.xml: contains preferences which were defined in the web UI during import
#       - e.g. `EnablePhotos`, `EnableChapterImageExtraction`, etc.
#   - config/encoding.xml: transcoder settings
#   - config/system.xml: misc preferences like log file duration, audiobook resume settings, etc.
#   - data/jellyfin.db: maybe account definitions? internal state?
