Nach der Installation bleiben ein paar Dinge zu erledigen um das System auf einen aktuellen Stand zu bringen und das System den eigenen Vorstellungen anzupassen.
Updaten
Achtung: dies entspricht nicht notwendigerweise dem best practice!
Als erstes einen entsprechenden Update Mirror heraussuchen und in der Datei /etc/slackpkg/mirrors die Zeile mit dem eigenen gewünschten Mirror auskommentieren (hier darauf achten, dass der Mirror zur Architektur der Installation passt (32bit oder 64bit) und dass in unserem Fall ein Mirror aus dem stable Branch ausgewählt ist).
Danach sind diese Befehle auszuführen:
# slackpkg update gpg
# slackpkg update
Damit wären die updates installiert. Das bedeutet aber nicht, dass die Distribution auf dem neuesten Stand ist. Man kann dazu noch ein Upgrade durchführen, damit alle neuen Programmversionen installiert werden. Es wird empfohlen, vorher eine Blacklist zu füllen, um zum Beispiel den Kernel nicht automatisch mit upzudaten. Wenn man dies jedoch möchte startet man noch den folgenden Befehl:
# slackpkg upgrade-all
Wenn ein neuer Kernel installiert wurde, muss nun noch zwingend lilo aufgerufen werden, jedoch schlägt dies das slackpkg Programm automatisch vor.

# PERSONAL $HOME/.bashrc FILE for bash-3.0 (or later)

# Last modified: Tue Nov 20 22:04:47 CET 2012
# This file is normally read by interactive shells only.
#+ Here is the place to define your aliases, functions and
#+ other interactive features like your prompt.
#
# The majority of the code here assumes you are on a GNU
#+ system (most likely a Linux box) and is often based on code
#+ found on Usenet or Internet.
#
# See for instance:
# http://tldp.org/LDP/abs/html/index.html
# http://www.caliban.org/bash
# http://www.shelldorado.com/scripts/categories.html
# http://www.dotfiles.org
#
# The choice of colors was done for a shell with a dark background
#+ (white on black), and this is usually also suited for pure text-mode
#+ consoles (no X server available). If you use a white background,
#+ you'll have to do some other choices for readability.
#
# This bashrc file is a bit overcrowded.
# Remember, it is just just an example.
# Tailor it to your needs.

Dies ist ein sehr extremes Beispiel der Anpassung der bash. Es gibt auch weniger stark eingreifenden Beispiele. Auf bashrcgenerator.com gibt es einen Generator mit dem Ihr euch ein Basislayout selbst zusammenklicken könnt.
Meine Empfehlung hier wäre: seht euch ein paar .bashrc Dateien an und dann erstellt eure eigene! Es gibt bspw. eine ultimate bashrc file mit etwa 18000 lines Inhalt. Das schiesst wohl etwas über das Ziel hinaus!
Bluetooth
Um Bluetooth in Slackware nutzen zu können, muss der Dienst bluetoothd gestartet werden. Ich lasse dies automatisch in einem init script mit starten:
/etc/rc.d/rc.local
#!/bin/sh # # /etc/rc.d/rc.local: Local system initialization script. # # Put any local startup commands in here. Also, if you have # anything that needs to be run at shutdown time you can # make an /etc/rc.d/rc.local_shutdown script and put those # commands in there. bluetoothd &
In den kommenden Tagen werde ich einen weiteren Beitrag mit mehr Konfigurationen für Slackware posten.
