Introduces passthrough.func, a Bash script to manage host-side passthrough configuration for VAAPI and NVIDIA devices in LXC containers. The script provides functions for USB, VAAPI, and NVIDIA device passthrough, including device selection dialogs, configuration file updates, and compatibility handling for privileged and unprivileged containers.
Replaces the inlined VAAPI passthrough logic in misc/build.func with calls to an external passthrough.func script, streamlining and centralizing hardware passthrough handling. Adds a new misc/passthrough.func file and introduces a hwaccel_setup_in_ct helper in misc/tools.func for hardware acceleration setup inside containers.
Replaces legacy VAAPI device detection and selection with a modular, more robust approach. Adds helpers for group ID resolution, device deduplication, and dynamic whiptail dialog sizing. Improves user prompts, error handling, and fallback logic for both privileged and unprivileged containers. The new implementation is more maintainable and user-friendly.
Refactors the LXC container network initialization to simplify IP wait logic, reduce gateway ping attempts from 20 to 10, and provide clearer status messages. Now warns instead of failing if the gateway is unreachable but the container has an IP, improving robustness in network checks.
Refactors the LXC network wait loop to use a for-loop with up to 20 attempts, providing clearer warnings and early exits when network and DNS are ready. Adds more robust handling for DNS failures by applying a fallback resolv.conf only after repeated failures, improving reliability and user feedback during container setup.
Improves readability and flexibility by building the NET_STRING variable incrementally, using parameter expansion to include only set values for MAC, GATE, VLAN, and MTU. This change makes the network configuration more robust and easier to maintain.
Improves package installation formatting, removes unnecessary device permission changes, and updates prompt to reference Debian 13 for the non-free Intel driver. Also refines user group addition commands for clarity and reliability.
