Allow cypht to run in another path

Reverse proxying Cypht docker, I need to put it in its own virtualhost (https://webmail.example.org). I'd prefer to use a subpath (https://example.org/webmail/). I believe that customizing the above symlink could do that.

dest="/var/www/$CYPHT_PREFIX_PATH"
mkdir -p "$(dirname "$dest")"
ln -s /usr/local/share/cypht/site "${dest%%/}"

Or in a more hacky way:

docker run \
  ...
  --entrypoint /bin/sh \
  sailfrog/cypht-docker:latest \
  -c "mkdir -p /usr/local/share/cypht/site; ln -s . /usr/local/share/cypht/site/webmail; exec docker-entrypoint.sh"
