Actually I'm going to install Slackware current so basically somehow it's rolling release and the fact that why I asked for a big official repository was my bad experiences with Slackware and it's dependencies anyway I decide to give it a second shot and use it for a while.

Good luck. There are some third-party binary repository for Current, mainly those which maintained by Slackware developers. As far as I know Slackel repository is compatible with Current too.

Apologies if this is a delayed reply.

I learned a lot about how Linux work by installing Slackware. You are in control of your distro, and you can easily customise it to your needs. If you are looking for a minimal install, you can remove many packages, or install with a minimal window manager was window maker, which comes bundled.

With respect to dependencies, slackbuilds.org lists dependencies clearly, your other option is ~alienbob

Slackware current serves the role of a rolling release.

I prefer SysVinit, of Slackware, I find it easily customisable to my needs.

It's exciting that 4 years after I started the topic. Exactly at the day that I re-installed Slackware you've posted a new answer on this topic.
