Preventing ComfyUI Custom Nodes from Overwriting PyTorch ROCm

The Problem

When using ComfyUI with an AMD GPU and PyTorch ROCm, installing custom nodes via ComfyUI-Manager (or manually via pip) can silently replace your ROCm-enabled PyTorch with the default CUDA version.

This happens because:

1. Custom nodes specify torch as a dependency in their requirements.txt
2. pip resolves this to the default PyPI torch package (CUDA version)
3. Your ROCm torch gets overwritten without warning

This guide explains how to defer services to start after graphical.target on systemd-based systems like Ubuntu with KDE Plasma.

The Problem

When you run systemd-analyze blame, you might see something like:
