Nah @exu is right: non-IT focused companies do not have the skills or desire to reliably set up and maintain these systems. There is no benefit to them creating their own server stack based on a community distro to save a few bucks.

Smaller companies will hire MSPs to get them setup and maintain what they need. And medium to large size companies would want an enterprise solution (IE: RHEL) they can reliably integrate into their operations.

This is for a few high value reasons. Taking Red Hat as an example:

1. Standardization (IE: they can hire people with RedHat certificates and they will be a few steps ahead in ramping up to internal systems)
2. Vendor support (IE: if something critical isn’t working they can get quick support from a Red Hat technician and get it resolved quickly)
3. Reliability (IE: all software is backed and tested by Red Hat and if anything breaks from a package update its on Red Hat to fix)

When lots of money is on the line companies want as many safety/contingency plans as they can get which is why RedHat makes sense.

The only companies that will roll their own solution are either very small with knowledgeable IT people (smaller startups), or MASSIVE companies that will create very custom solutions and then train their own IT operations divisions (talking like Apple, Microsoft, Amazon levels).

Not to say what Red Hat did is justified or good, because hampering the FOSS ecosystem is destructive overall, but just putting this into context.

From a user perspective, Distrobox is a tool that lets you “spin up any distro inside your terminal”.

You can basically create a mini Linux environment of any distro that you can access through the terminal. You can set it to share your home folder, our create a new home folder just for that mini environment.

Behind the scenes Distrobox is creating and managing containers through Podman or Docker. You could technically achieve the same thing by manually setting up Podman containers, Distrobox just makes it very easy to create and maintain those containers with the correct permissions. It also has useful tools where you could install an app in a Distrobox container, but then add that app to your host OS app list.

This makes it especially useful for immutable OSs. Instead of adding packages to your base OS, which should be kept as minimal as possible, you can just install them in a Distrobox, so your host’s root filesystem is unaffected.

I daily drive Fedora Silverblue on my laptop and distrobox has been great.

I have layered only two packages: USB Guard and Distrobox. I run syncthing in a rootless podman container, and the rest goes through Distrobox.

I was even able to setup ProtonVPN in distrobox and it functions as if it was directly installed on the host (just need to map your home folder and some permissions).

I hope that immutable becomes either the standard or at least all major distros start offering it as an alternative. Makes everything foolproof and makes me much more willing to try new packages and tools because I can always just roll back.

The only thing that would really make it perfect is if files in /etc/ where also handled in a similar manner. IE: Can make changes to configuration files, and easily roll back to defaults at any time.
