On Linux:

Uninstalling Unimus Core is different depending on if your system runs the "systemd" or the "sysv" init system.

...

Simply use the "Add or remove program" Windows utility to uninstall Unimus Core.

The uninstaller will remove all Unimus Core files, but not user-created files (such as config file, the embedded HSQL DB, etc.).
After the unintaller is finished, you might also want to remove the directories that are not removed if there are any user-created files.

These are:

• C:\Program Files\Unimus-Core
• C:\ProgramData\Unimus-Core
