CentOS 7 to 8 upgrade scripts

What this script does:

1. It creates a "Minimal" install of CentOS 8 in the new_root diretory;
2. It copies over only the essential files to new_root;
3. It pivots / with new_root;
4. It obliterates everything you have in /;
5. It copies everything in new_root to /;
6. It pivots back to /;
7. It obliterates new_root.

Install:

git clone https://github.com/yuusou/eight-ate-seven.git

Usage:

bash 887.sh /8 # or some other, temporary directory you wish to use.

Notes:

• SELinux needs to be disabled first.
• This hasn't been tested in the wild.
• To see further use cases (such as running a pre-script script or a post-command, run bash 887.sh without arguments.

TODO:

• Create functions for each step;
• Merge all three scripts into one;
• Remove need for having script in specific location;
• Fix running commands and running scripts, currently not working;
