Comment on Silverblue or other immutable on remote VPS?

  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.

      They 100% can.

      It’s a read-only filesystem:

      /dev/nvme0n1p4 on /sysroot type xfs (ro)
      /dev/nvme0n1p4 on /usr type xfs (ro)
      /dev/nvme0n1p3 on /boot type ext4 (ro)

        An attacker escaping from a container can’t be system root as Podman runs rootless (without some other exploit or weak password).

        That would be true of podman running anywhere, and is not unique to an immutable distribution. This is also clearly not what they are talking about.

        The filesystem itself is also read-only.

        You can change that real quick if you have root access.

      Absitively, use case here IMO is set and forget autoupdate to stay current and SELinux (which actually reduces surface)

    Wait, why wouldn’t they? They could wipe the entire disk if the so choose
