Which ticket is this? The rollback was actually disabled to allow 
troubleshooting the failed installation:

It's not official, but we call this step pki-nuke.

Rather than rolling back the installation automatically (and delete all 
files needed to troubleshoot the problem), it would be better to provide 
an option to the uninstall command to forcibly remove all installed 
files regardless whether the installation was successful or not, just 
like the pki-nuke above.
