Install minifest - default programs?

This may seem a little strange to long term unix users but is there a manifest of default installation programs (and their dependencies)?
Everyday, I get update messages for one or more programs.
Some of these updates are to programs I never use and never will use.
I do understand that some programs may well be “shells” or rely on other programs for functionality, and that is fine.
BUT…how many of the running processes and daemons are there just in case?
As a desktop environment windows users as a collective “generally” do the same sort of things with their computer (email,browsing, document writing, photo viewing some do graphic manipulation, archiving playing games).
There are a few things that are common to mobiles that they take for granted like weather news etc, but if they weren’t there they probably wouldn’t miss them.
On unix there are many many different ways of doing the same thing. We have a myriad of choice.
Rightly so.
But a lot are “legacy” programs left there because developers and long time users prefer to use terminal as their interface. We are creatures of habit and prefer things we know. We may try new programs but unless they offer significant improvement, we stick with what we know works.

So is there a manifest of all programs installed, so that I might go through and reduce my system to the minimum I use?

The defualt set of applications is going to vary depending on the distro, as they have the final say on what is included for both the OS level and desktop level applications, services, and libraries.

On Ubuntu -like distros, the installer ISO will contain a manifest located in /casper of not only the individual packages that are includes on the OS image that is blasted to the drive, but also one for the things removed afterwards if one uses the ‘minimal’ install option. However, this is not Plasma specific nor is it clear, as it list individual package names which as usual are quite cryptic for us mere mortals.

A Starting place for Plasma specifically:

To be honest, starting from the bottom and working up, and only including what you want from the start (aka Arch or similar) may be the better way to go than to rip out what might have been set up for you (aka Ubuntu/Fedora/Debian and similar) which may lack a fine-grade way of doing so without inadvertently damaging some other parts, even if this is not likely.

Thank you for your reply @claydoh
I actually suspected as much but I hoped someone else thinks a bit like me :grinning:
Thanks for the link, I will attempt to digest it and come up with a list.
