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.

That phrase has practically lost all meaning.
Because even if an attacker could gain access even as root he cannot modify system files. This is why immutable OS distros are called immutable.
They 100% can.
An attacker escaping from a container can’t be system root as Podman runs rootless (without some other exploit or weak password).
The filesystem itself is also read-only.
/dev/nvme0n1p4 on /sysroot type xfs (ro) /dev/nvme0n1p4 on /usr type xfs (ro) /dev/nvme0n1p3 on /boot type ext4 (ro)That would be true of podman running anywhere, and is not unique to an immutable distribution.
You can change that real quick if you have root access.
