I agree, and I think the author was unfortunately using coreOS because it's uncommon for cloud providers to have coreOS images nowadays, and therefore a good opportunity for him to slip in a referral code for VULTR.

Is coreOS even maintained any more? I wouldn't expect it to be very secure if the most recent VM images were built in ~2020.

Would love another writeup just using Ubuntu or some other bog-standard Linux distro.

CoreOS was acquired by Red Hat, and now "Fedora CoreOS".offers similar concepts.

Conveniently, RH also invented both Podman and systemd.

Note: similar, but definitely not the same. The real continuation of CoreOS was Flatcar Linux (https://www.flatcar.org/), but then the company behind that was bought by Microsoft (https://kinvolk.io/blog/2021/04/microsoft-acquires-kinvolk/) and I really don't expect much of them anymore...
