Various scripts and tools that we find useful, whether we use them or they are
made for public consumption. For example, conversion scripts or otherwise.
## [Centos2Rocky] -- Conversion Script
Running this script will convert an existing CentOS 8 system to Rocky Linux 8.
### Usage
```bash
./centos2rocky.sh -h
├── -h # --> Displays this help
├── -r # --> Converts to Rocky
├── -V # --> Verifies switch
└── -R # --> Reinstalls all packages
[!! USE WITH CAUTION !!]
```
.
├── centos2rocky.sh # Converts a CentOS 8.3 system to Rocky Linux 8.3
└── README.md
```
### Debugging
The `centos2rocky` script pipes everything shown on `stdout` to `/var/log/centos2rocky.log`.
If you run in to issues executing this script, please submit an issue [here](https://github.com/rocky-linux/rocky-tools/issues).
Make sure to [include the output log](https://pastebin.com/), and remove any sensitive information. (if any)
Feel free to create a pull request if you think you've got the fix.
