For all those slackers who were waiting for the option, there is an
updated document in the wiki.
https://tools.bitfolk.com/wiki/Installing_Slackware_14.1
It shows how to install slackware 14.1 (32bit) onto a bitfolk vps. It
uses a simplified partition format (ext3) and hopefully a greatly
simplified procedure (originally based on
https://tools.bitfolk.com/wiki/Installing_Slackware - many thanks for
the good work there.)
It isn't supported by bitfolk, but at least it works (tested on my own vps).
regards, Tim
