I created an ebuild for serviio 2.3.0, I took the original from https://bugs.gentoo.org/505034 and modified to new EAPI and new ebuilds to create user and group serviio. i'm not really sure about the UID AND GUID i just chose something random. tested on ~amd64 with systemd, didn't test the init.d scripts. Reproducible: Always
Created attachment 863427 [details] ebuild to create serviio user
Created attachment 863428 [details] acct-group/serviio/serviio-0.ebuild ebuild to create serviio group
Created attachment 863429 [details] net-misc/serviio-2.3.ebuild is net-misc the right category? the original one used this category, serviio is a streamer app
Created attachment 863430 [details] systemd.service
Created attachment 863431 [details] systemd.service.conf a conf file to allow mounting directories before starting serviio, i didn't test it since my partitions are at /etc/fstab so it wasn't needed
