Arch Linux

Hey everyone. So I need to make a custom iso because I don't have access to the router from my apartment and my wifi antenna uses the rtl8192eu driver, which is not included by default. Hence, I decided a custom iso was the way to go. I don't want however to bloat it up, and since I'm making it on my laptop which is running Endeavour OS I can't trust the packages.x86_64 file in the releng directory to be the default plain arch install package list (following the archiso instructions on the wiki).

So what I am actually asking for: Before building my iso, what are the packages that the actual maintainers of Arch Linux would put in the packages.x86_64 file, which we would have access to from the live environment, that I should also include (plus the 5 packages I want to make sure I have, which is the custom part of this iso)?

How I understand it reading the install guide as well as a couple forum posts, the only truly necessary packages for an arch installation are base, linux, and linux-firmware. Correct me if I'm wrong please. After installing archiso on my endeavour os laptop I had around 130 packages in my packages.x86_64 file. Many seemed unnecessary.

Thanks in advance!
