Thoughts about importing a package manager

With the shell script you wrote, it looks like Peropesis 1.8 works. I've changed some VM options a little bit:

exit

#The end

Could I add this script to the user manual, creating a new chapter named: "Peropesis live booting by using managing VirtuaBox from CLI"?

Regarding the testing, I agree, which is why I take your comments very seriously (due to the need to install a text editor, SQLite and a larger screen). Once these tools will be installed, it will be easier to write programs and when the programs will be written and it's time to compile them it will be clear whether the compilers work well or not.
