Although the user can manually delete these files before repacking the customized ISO, Cubic should exclude these files from the final ISO.

Particularly, the bash command history (stored in the .bash_history) is hard to clear because this file is not always flushed to disk immediately. Furthermore, any command used to clear bash history (i.e. `history -c`) will clear the history, but this last command will actually get stored in the history. As a result this last command will appear in the root user's history after the customized ISO is installed.
