I have been kicking this idea around for awhile and finally had the time to write something. I call it Slack-Serv. What it does is take all these min install of slack and install the needed packages to be able to customize the server to your needs. It installs wget install then uses that wget install to download and install slackpkg. After that is installed you should be able to update and install any slackware packages from the repos you configure in slackpkg.
I also included iptables for the security people.
This is aimed mostly at servers and vps that only offer minimal installs of Slackware. I wrote it for Slackware 13.37 but you should be able to modify it to any Slack.
