- Split up initialization functions and process supervision. Process supervision stays in entrypoint.sh, whereas the initialization functions are moved to individual files in /etc/entrypoint.d.
- Apache runit script also needs `setup-runit.sh` option; force.
- Fixed the Apache runit script, using the new `setup-runit.sh` script. Stopping the parent process now also stops all child processes. Using the quiet option, Apache does not flood the logs anymore.
- Added support of the environment variable `LMTP_LISTEN=*:2003`, due to misconfiguration of `kopano-dagent` in recent releases (8.7.84).
- Simplified the health check.
- Changed repository directory structure to a more general one.
- Renamed some build variables, e.g., `DOCKER_RUNSV_DIR` (was `docker_build_runit_root`).
- Cleaning up `Makefile`
- Added more debug functionality in `demo/Makefile`
- Demo based on `docker-compose.yml` and `Makefile` files
- Check and fix file attributes in the `/var/lib/kopano/attachments` directory
- Updated Tags overview, Usage and Docker compose example section in README.md
