The "gutter oil" Linux distribution is Fedora, which is basically the same as Red Hat, except that the kernel and software used are the latest versions, which means it is very unstable. On the one hand, because those software (including the kernel) may be changed in subsequent updates. On the other hand, the latest version of the software has not been tried for a relatively long time and many problems have not been exposed. The only advantage is that "the technology used is the most advanced" and is suitable for those who purely treat Linux as a toy to learn and use.

Linux distribution "Big Lizard" is SUSE, which is a Linux distribution issued and maintained by the German SuSE Linux AG company and is a registered trademark of this company. In 2004 the company was acquired by Novell. Originally named SUSE Linux, SUSE Linux released after version 10.2 was renamed openSUSE. The SUSE Linux Enterprise version is a commodity and only provides free trials to users. Long-term use requires purchasing service support and upgrades from Novell. The latest version of openSUSE is version 13.1. The next version 13.2 will be released in half a month (15 days).
