i figured there had to be some free version. i was wondering if it could be done from Ubuntu, even if not as small, that i could run on my 16GB RAM laptop from one of my 32GB memory sticks. i made some from Slackware back in 2012/2013 for some servers. but after the pretty boot menu i made to pick a kernel, it just brought up a text mode command line (about all a server tool needs).
