I believe so.
I will try but , probably core system it s too much for me.
The most high-level program in a minimal NetInstall must be apt!
And aplications like abrowser are not in the repositories by default I guess.
They are. All packages are in the repository.
You can install a minimal (terminal-only) system with a NetInstall and then
'sudo apt install' the sole packages you want.
I want to rid of samba, wifi , bluetooth, ssh, ... I just want an internet
browser and an email client.
You had better 'sudo apt install' on a fresh NetInstall.
