OSTechNix has written an excellent article about How to create persistent live USB on Ubuntu.
I’ve tried Mkusb today and it works perfectly well. Unfortunately not on my derivatives of Ubuntu. I.e. all ExTiX versions. That’s because they are made with Refracta Snapshot. You’ll have to use an Ubuntu original ISO image. I myself used eoan-desktop-amd64.iso (Ubuntu 19.10). As promised I could save all system changes directly on the stick. Persistence! Watch a slideshow below showing the install process.
Slackware is the first widely-used Linux system, which is still developing. Slackware has existed since 1993. In comparison with for example Ubuntu and Linux Mint, many people believe that Slackware is “difficult”. Any novice can quickly learn to use Ubuntu they say. My remaster of Slackware Current (14.2), which I call SlackEX 14.2/Current 64 bit Linux Live DVD, is however just as easy to use as Ubuntu and/or Linux Mint. Some tend to complain that the Program Management in Slackware is awkward. That was perhaps earlier the case, but not anymore. Now we have the Application Managers Slackpkg and GSlapt – a GTK version of slapt-get. They are a piece of cake to use! Users of Synaptic will feel at ease with GSlapt.
New features in version 191007 of SlackEX
I have replaced kernel 4.14.8-x86_64-efi-exton with kernel 5.3.0-exton so that Refracta Snapshot can be used. Using Refracta Snapshot you can change everything and create your very own live installable Slackware system. Read more about Refracta below. Xfce 4 is used as Desktop environment. Furthermore I have installed Grub2, which can be used as boot loader (if you want) after a hard drive install using Refracta Installer. A lot of other Slackware packages are pre-installed. Study the full package LIST. Note: I have replaced Wicd with NetworkManager. It works better.
