ERROR: Unknown Linux distro: unknown

Is it necessary to know the linux distro? If it's failing on the service step, would it be more viable to have an option flag for using systemd or openrc/init.d and skip distro detection? I haven't looked into the code yet so I don't have much context to this error. Would you support having Gentoo as a known distro if I worked on adding it?

I know Gentoo but never used it, but I think is more used in desktop than servers.

The install automatically install some third-party dependencies like LibreOffice and I don't even know which package manager uses Gentoo. Anyway, the installer helps but If you want to install OpenKM in Gentoo you can also make a manual installation (download Tomcat, download OpenKM and configure it). Please, check https://docs.openkm.com/kcenter/view/okm-6.3-com/installing-on-ubuntu-and-debian-(manual).html

I'm assuming that I'll be able to view the article once I create an account. It might make more sense to create an ebuild for gentoo specifically instead of modifying your script, so that gives me a good direction to look in.

Thanks for your help. If/when I get that done, I can reach out again. Cheers.
