Comment 13 for bug 1840232

I don't think that typing exit would cause the issue...

Cubic applies custom colors by momentary modifying /root/.bashrc.
The original /root/.bashrc is immediately reinstated once the chroot environment is running.

However, when you manually exit, Cubic restarts the chroot environment, but it doesn't do the "trick" with .bashrc.

Also, if a user modifies the .bashrc file in /root, the user's changes will be always saved and included in the final generated ISO.
