Silverblue or other immutable on remote VPS? (self.selfhosted)

Does anyone know of a hosting service that offers Silverblue as a possible choice for OS?

It seems to me that for a server running only docker services the greatly reduced attack surface of an immutable distro presents a definitive advantage.

While what you're saying is theoretically true, don't forget that as far as I know, most attacks are perpetrated by bots. And while it is true that in a fedora based version one could run ostree admin unlock etc... this particular command would need to be included in the attack script.

Now if the script has to be modified to include all possible different immutable systems that could possibly run it would increase the complexity and most importantly the size of said script making it easier to detect.

I'm not saying that its a bulletproof method, I'm just saying that by itself it greatly minimizes the risk, at least until all servers run immutable systems. And even then it still complicates matters for potential attackers quite a bit. So therefore reducing or at least greatly minimizing the potential of the system being compromised.

Because even if an attacker could gain access even as root he cannot modify system files.

Your comment was already from the position of if an attacker could gain root access. My responses were to that directly, and nothing else.
