 + + X                : Add support for X11
 - - abi_x86_32       : 32-bit (x86) libraries
 + + dist-kernel      : Enable subslot rebuilds on Distribution Kernel upgrades
 + + kernel-open      : Use the open source variant of the drivers (Turing/Ampere+ GPUs only, aka GTX 1650+ -- recommended with >=560.xx drivers if usable and it may be required for 50xx Blackwell+ GPUs) 
 + + modules          : Build the kernel modules
 - - modules-compress : Install compressed kernel modules (if kernel config enables module compression)
 - - modules-sign     : Cryptographically sign installed kernel modules (requires CONFIG_MODULE_SIG=y in the kernel)
 - - persistenced     : Install the persistence daemon for keeping devices state when unused (e.g. for headless)
 - - powerd           : Install the NVIDIA dynamic boost support daemon (only useful with specific laptops, ignore if unsure)
 + + static-libs      : Install the XNVCtrl static library for accessing sensors and other features
