 Install the resulting `deb` file and we're set - LibreOffice Online, in a Debian package. To install it on another machine, all we need are the packages generated by this guide (`libpoco-dev` and friends, and `loolwsd`).

+### Bonus - Changing the LibreOffice Online directory
+
+By default, the LibreOffice Online package installs the main configuration of the `loolwsd` service under `/opt/lool`. I'm not a fan of putting anything under `/opt` however, and in BLSE2 everything that is per-server and not automated via configuration management goes under `/srv`. If you also desire this, it's very straightforward to edit the Debian configuration to support installing to an arbitrary target directory before building the package.
