I think the least that distros can do, is allow listing all packages and system settings in config files like .toml rather than having to type in every single package to install, or click through system setting GUIs to setup. Would that require using a whole programming language or system like NIx?
While NixOS works much differently from most distros, that’s the only reason I use it: package and system settings in text files. If I fix something, it’s fixed permanently, I don’t need to hunt down files in random directories if I want to change a setting. If I ever need to reinstall the OS I don’t have to write dnf install every single damn package and manually setup all that up all over again. Having daily-drove Windows macOS & Fedora as throughout the years, my setups have felt hacky as well as houses of cards as I’ve wanted or had to set them up again (I don’t mean Fedora specifically, but distros in general).
Basically it feels insane that it’s the way most linux users and servers in the world operate. If I, a humble computer hobbyist can figure out Nix, why don’t more users do so, and why is Nix so niche?
You can backup your list of packages to .txt and install from .txt using
aptso I don’t really know what more you would need. I literally just did it last week to install a new distro.But then you need the pins and repositories you had before. I end up pasting a long ass chain of commands every time I get a VPS up just to set it up.
You don’t backup
/etc/apt/sources.list.d?I’d have to also back up /etc/apt/preferences.d
Much easier to just copy and paste a block of commands when I get a VPS up
Well, that’s up to you and your system. I just backed up the sources list directory and called it a day because I’m on Debian stable and use very few other package sources. I’m okay with a small degree of reconfiguration on the system drive since I have everything else on separate disks.
