Installing Absolute.
The Absolute installer is text-based.
You can install via the basic steps used by Slackware (which can be difficult for newer users but very flexible for experts) or you can choose the "autoinstall" option.
The main advantage for autoinstall is that it skips the need to run 2 sections of the configuration -- disk partitioning and lilo (boot loader). DO NOT use autoinstall if you are not using the entire hard drive for Absolute or if you like to partition the drive manually.
If you are ok with only Absolute on the drive, autoinstall will save you a LOT of time. I suggest you look over this page of the initial installation, as well as the Configuration page before you decide.
