Per these:
What's the consequences if I don't install the "standard system utilities" of Debian?
https://www.debian.org/doc/debian-policy/ch-archive.html#s-priorities
there are three priority levels of packages:
requiredimportantstandard
I understand that required packages are installed by default. standard packages are optional and can be selected during installation.
What about the important ones?
Are they also installed by default?
Thanks
