@pushcx OK, bootstrapped a NixOS install and starting to learn to configure it. So far still easier than contacting DigitalOcean about their billing bugs.

I might be a bit late on this, but I wrote a guide for Linode on this when I still worked for them:

@nixy That would've saved me a couple minutes of hassle, thank you for the thought. I'm writing up my notes in a blog post to share, too.
@pushcx Five attempts to contact them got 1 error and 4 bot autoreplies. Partitioning and installing grub only took 4 tries.
