You might have noticed already, the Linux homeserver project is not updated for a very long time. The original setup was based on Slackware 14.0 and some parts were updated to version 14.1. Version 14.2 is already released a long time ago, and a next version will be announced anytime now. Well, within a year “when it’s ready” of course.
I will leave that project as it is now, it doesn’t look like my own setup anymore, I just keep it as a reference so you can borrow some ideas from it.
