Agreed - for someone moving from Windows / Mac, the immutables and flatpak are the way to go now. It’s going to take a bit for the Ubuntu / Mint crowd to change their song. Bazzite in particular is a huge olive branch to the gamers. Even for someone who is “tinkering” learning distrobox and/or flatseal can enable most things you would ever want to tinker with on a desktop. If you are really developing something, chances are that you use containers or a VM anyway.

I have to concur on flatpaks though: they have room for improvement. More validation / trust is needed, and the options are wide open. For non-technical users, the *surety and security *isn’t necessarily on par with the app stores of Microsoft, Apple & Google - though the experience is getting there.

Using computers since before GUI was available… Sometimes I think we ought to go back to it

If you had installed bazzite those kids would worship you

Late to the party, but I’ve read that OP is going to be the sole admin. Do Not Do This. I admire what you are trying to do, but ultimately, you will have no rest, no vacation, no backup for yourself. The hardware & software aren’t the issue here - it is the human support of those services. You will put a single point of failure on yourself, and likewise your peers.

Many of the FOSS projects you mentioned have commercial services. SAAS exists for a reason. By subscribing to those services as a business, you underwrite their ability to provide the software for free to the community. It’s a win-win.

I just use SMB shares on my NAS. Why over think it?
