This is what I do for a lean (not necessarily minimal, but trimmed to my liking) installation. Will continuously update this based on my latest experience.

• official packages (getslack)
  • without kde & xfce (checkout my getslack config file below)
  • removepkg: gnuchess, xaos, xsnow
  • removepkg: joe, nano, vim-gvim, slackpkg
• setup/config
  • make sure vim does not create backups (edit /usr/share/vim/vimrc)
    • or, run vimstart (from my1shell repo)
  • dmesg no longer allowed for user
    • append etc/rc.d/rc.local ← echo 0 > /proc/sys/kernel/dmesg_restrict
    • or, run setup_slack (from my1shell repo)
  • setup acpi from my personal script
• additional packages (getslackpack)
  • (alien) openjdk libreoffice libreoffice-dict-en“
• additional packages (getslackbuild)
  • dmenu slock st wmname
  • slackware-xdm-theme
  • geany rox-filer pmount unrar
  • nss-mdns avahi libdaemon
  • scripts from slackbuilds.org all gathered here
• custom dwm build
  • using my own build script (which has personalized patches)

To maintain:

• run slack-update
  • this actually runs 3 scripts (getslack,getslackpack,getslackbuild)
• run slackpatch (if required)
• run getslackbuild build -x -i (if required)

Sample configuration files for the above scripts are here.
