I installed many additional packages on my PC. dpkg --get-selections
command displays all the installed packages. From the installed packages how do I know which are important for system booting (if we remove any one package from the important packages list, system won't boot or system doesn't appear like normal).
If I know that, I'm aware of it and I won't remove these kind of important packages. So how do I know that these packages are important and these packages are not important from the output of dpkg --get-selections
?
