# Usage (from Proxmox host):
#   pct exec <CTID> -- bash -c 'cat > /tmp/bg_install.sh; chmod +x /tmp/bg_install.sh; nohup /tmp/bg_install.sh &'
#   (paste this script via heredoc or copy with scp)

# Poll progress:
#   pct exec <CTID> -- tail -20 /tmp/bg_install.log
#   pct exec <CTID> -- cat /tmp/bg_install.done 2>/dev/null && echo "COMPLETE"

# --- 1. Optional: ROCm userspace (if not yet installed) ---
# amdgpu-install --usecase=rocm --no-dkms -y

# --- 2. Optional: PyTorch ROCm ---
# pip install torch torchvision torchaudio \
#   --index-url https://download.pytorch.org/whl/rocm6.2 \
#   --break-system-packages

# --- 3. Application dependencies (e.g. ComfyUI) ---
# cd /opt/ComfyUI || exit 1
# pip install -r requirements.txt --break-system-packages

# --- 4. Prevent Debian system packages blocking pip ---
# If pip fails with "Cannot uninstall X, RECORD file not found",
# remove the conflicting deb package first:
#   dpkg --remove --force-depends python3-rich

# --- Mark completion ---
