I'm looking into advanced distros (like arch) and slackware is fascinating. Is it still supported/used? If you'd like to comment an alternative distro, please do.
I've only barely gone beyond the more "backup + Docker appliance" style front end of Unraid, so I'm not sure. They make it extremely difficult for the untrained to get where you can break stuff. I am mostly an Arch/Debian guy.
I'm a guy who prefers community based distros. They don't have business decisions get in the way of the needs of the community. It ain't perfect, but it's worth the tradeoffs for me. Debian for stuff I don't want to constantly mess with. Arch for the express purpose of constantly messing with (and sometimes messing up).
Man, I might have to look into using Slackware again for the first time. No matter how much more comfortable I've become with systemd, I still hate it with a passion. If Slackware can handle at least XFCE well, preferably Cinnamon, it's worth diving back into. Been 25 years though.
If you can manage a Linux server, you likely have no use for Unraid. If you want to put together a Synology type appliance out of PC hardware to run Docker containers and uses ZFS for backups, Unraid is a fairly user friendly option.
