Earlier this year, I built a new PC and it’s running Ubuntu. I’ve been installing various apps and configuring them since then. Now, I realize I don’t have any way of knowing what I would want to reinstall, if I (for instance) lost this drive somehow.
How do you keep track of what you’ve installed/ your favorite apps?
Separately, how can I backup the configurations I’m using right now.
Thanks!
Git.
Keep all the config files of your tools in subdirectories of a git versioned directory and symlink them into their target location (e.g. with GNU stow). If installation of a tool is involved and you expect to have to revisit it, put the steps into an installation bash script and version it as well.
+1, essential ones I keep in GitHub repository (like zsh, tmux, xdefaults configs with no personal data). With makefile that makes symlinks. This is the easiest way to sync zsh config between my personal and work machines.
Rest is just in a backup.
Do you have an example of a generalise makefile that does that? Or does it need to be customise per configuration?
On my GitHub repo. Needs to be customized, but you should get the idea.
Maybe there is a way to write it better, I’m no makefile expert ;)
Seconding this. Store your configuration.nix in git and just copy it back over if you ever need to wipe and reinstall.
Oh! I can participate!
Everything I have/configure is 100% in Ansible. I learned the hard way that rebuilding a workstation from scratch sucks if I only depend on my brain to remember things.
It takes some effort to keep it updated - if I’m trying out a new app, I have to remember to add it to my config.
The other thing that I’ve started doing is using Restic for file level backups. That’s relatively easy to set up, it supports a multitude of backend storage, and works well with a cron job for braindead backups.
Home Manager on a NixOS flake, it’s a rabbit hole but I’ve been loving it since last week!
I just check my Nix.config, but most distros don’t have that privilege.
Idk how it works for most other distros, but I know on Arch you can check all packages manually installed by pacman and your AUR helper.
Iirc
pacman -Qe
does something like this
Install fresh copy of Linux OS on a new device. Install the apps I know I need like browser, code editor, etc.
Use device.
Realize “oh crap I forgot to install X!”
Install X
Repeat until all X have been installed.
Lol, pretty much what I’ve done in the past. And yep, it works, eventually.
Home manager on NixOS and stored all config files in a Git repo
Backup $home and /etc. That should be good enough.
Yes, my concern with this is that I have Steam installed and its games are many many GBs. If I do a backup I’ll have to exclude that folder. I’ll try this and see how it goes. Thanks!
I make a list of all the ones I like. Then when I feel my system is getting too bloated, I wipe and reinstall while only installing the packages from my list.
It’s very “low tech,” but it’s always worked out well for me.
Yes, I think this is more like what I’ll do, though I like the idea of a git repo for the configurations. Cheers
NixOS stores a snapshot of your OS and all the app configs in an OS config folder for you. Helpful for instant system recovery or deploying the setup to new hardware.
Lately using Silverblue. Everything is a flatpak or is layered. Both are easy to list.
Maybe a handful of things in distrobox I need to keep track of.

I typically start with a restrictive .gitignore and add directories as needed.
A ton of stuff that I always forget like mpv, vifm, and whatnot always slipped through the cracks before. Now I can clone to practically anywhere and have everything just work.
If you use other package managers like
flatpak
,nix-env
(for non-NixOS),npm
(for global stuff), … you can just create a bash script to list all installed packages for each manager, and save to a file(s). I put them in a git repo to version control these lists, which are updated every now and then when I update stuff.I keep a changelog for all my computers and note installations, uninstallations and config changes.
