I’m wanting to create a centralized repository to keep base images of operating systems to be installed on new laptops or workstations bought/used in my household with my local CA already installed, configured to authenticate with my local FreeIPA instance, network configurations already configured, etc.
What do you all use to accomplish this? I’m only free/libre/open source software for my home lab, so that’s a requirement as well.
Ideally I’d like to be able to buy a computer, flash the latest and greatest from my repository onto a bootable thumb drive, install onto the computer, and be ready to go without any further configuration.
If you want to use OpenSUSE leap as your OS autoyast is made for that: automatic installation and configuration of new systems without (or with minimal) attendence
Or you could write an bash script that makes all those configurations and just run it after finishing the Install.
An ansible playbook would be another option to do these configurations semi-automatically
I only tried this with windows which works fine: on restore Clonezilla has an option to rescale partitions on the fly to fit the destination drive. For drivers, windows detect changes and update them the first time is started on the physical machine.
I set this up for production on a factory floor for others to use. It’s nice, works extremely well once set up. Importing and exporting images could be easier.
I have a set of shell / powershell scripts that I run post-install to configure everything.
They are hosted on a local webserver, so it is just a one-line command to run the appropriate one.
This is something NixOS excels at, but there is a bit of a learning curve. Maybe ansible as a non distro specific approach although I haven’t used it myself.
I’ve used commercial systems that provide what you are asking for. I’m not sure it is worth the time to setup for a home lab. I don’t see the ROI for it. Too much initial setup for the small gains afterwards.
I expect you’ll want to bake in a install config and likely a update-all.sh of some sort to each image you want to deploy. I think the frequency of that is the major time suck unless you only use LTS releases.
That said I think a PXE boot server is what you may be looking for.
I had a pxe server for my house a few years ago, and the effort maintaining it well outstripped the savings, especially for windows images. It was useful for learning, but not for real life usage.

Clonezilla. I usually prepare images in virtual machines and restore them on physical drives.
How do you deal with the hardware differences between a virtual machine and actual hardware?
I only tried this with windows which works fine: on restore Clonezilla has an option to rescale partitions on the fly to fit the destination drive. For drivers, windows detect changes and update them the first time is started on the physical machine.
I liked fog a few years back
I didn’t actually implement it, but it looked like the winner last time I looked. I’d also recommend starting there.
For work it’s all Windows so we use MECM.
seems likea FOG server: https://fogproject.org/ is what you need.
A awesome project and greatly simplifies the PXE boot process. You have a repo of images you have setup ready to go and be installed.
