I understand that /var/www/discourse/vendor/data/ is used to store the GeoLite2-ASN.mmdb and GeoLite2-City.mmdb map files.

I noticed there’s also an RT\_sRGB.icm file in /var/www/discourse/vendor/data/. What is this file used for, and what is its primary function?

I’m deploying Discourse using containers and want to mount /var/www/discourse/vendor/data/ to a host directory:

```plaintext
  - volume:
      host: /opt/1panel/apps/discourse/shared/standalone/vendor-data
      guest: /var/www/discourse/vendor/data

```

In the future, I plan to manually update the map files GeoLite2-ASN.mmdb and GeoLite2-City.mmdb on the host (since my MaxMind account cannot automatically download GeoLite2-City.mmdb). Do I need to also transfer the RT\_sRGB.icm file to the host directory: /opt/1panel/apps/discourse/shared/standalone/vendor-data? If I do transfer it, I’m concerned that the RT\_sRGB.icm file might get updated.
