It’s always been known that once you install cPanel, you cannot uninstall it, the only way to get rid of it reinstall the server completely. However, I was doing some work on a server and ran into this file:

/usr/local/cpanel/uninstall

And the content:
#!/bin/sh
# Uninstall script for Cpanel
rm -f "/usr/local/cpanel/uninstall"
#### END OF UNINSTALL
echo "Cpanel has been uninstalled."

Nice to know that developers still have a sense of humor. cPanel’s developers are always known to be down to earth guys and I can assure you that’s true! (not if that little bit of code in a production program didn’t prove it! )
