Can you clarify under which scenario(s)?. I guess what you propose is
to enter the temporary system by entering `enter-chroot` and install the
packages instead of having to build the whole final system, right?.
You are almost right. I wanted to say that when we have an instance of qi and set of binary packages, we can install only part of the packages. It will give us a filesystem representation of dragora but in this case we can decide what we want see in the live image. So it means that we can provide core dragora image. It also means that user can create custom image with only necessary for the user packages. In this situation we have one special case. If we will install all binary packages, we will get the whole final system but it doesn't have much sense because when we follow instructions from `CHEATSHEET.md` we compile all packages and install them so we get the whole final system in this way (It can be useful for the user when user has all binary packages and installed qi and wants to produce dvd iso image).
