Yes… and no! Actually during the image build, we must use dnf (because we’re not in a running system) and we can modify any directory as we would in a classic distro. It’s only once the image is deployed that we need to use rpm-ostree to manage packages.
Docker applies a default seccomp profile that blocks around 40 to 50 syscalls. This meaningfully reduces the attack surface. But the key limitation is that seccomp is a filter on the same kernel. The syscalls you allow still enter the host kernel’s code paths. If there is a vulnerability in the write implementation, or in the network stack, or in any allowed syscall path, seccomp does not help.
