"""Idempotent vLLM deployment script for AMD ROCm GPUs.
Deploys vLLM behind nginx with self-signed TLS on Fedora or openEuler.
Deploys vLLM behind nginx with self-signed TLS on Fedora, CentOS Stream, or openEuler.
vLLM binds to ::1 (IPv4 loopback fallback) on port 8000, internal only;
nginx proxies :443 → the loopback upstream with streaming (SSE) support.
The endpoint requires an API key, delivered to the service via a 0600
EnvironmentFile; nginx→vLLM proxying is allowed through SELinux on
enforcing systems. Fedora gets ROCm from its native repositories;
openEuler falls back to AMD's amdgpu-install (unsupported by AMD).
CentOS Stream and openEuler fall back to AMD's amdgpu-install (unsupported by AMD).
No external dependencies — stdlib and system tools only. Every operation
checks current state before acting; running the script repeatedly produces
