dramatically speeds up my boot time because it was the last
service (for me) that depended on udev-settle.service
udev-settle isn't needed for modern system initialization but some
oldschool services (mdadm/lvm/cryptsetup) depend on it so they can
just enumerate devices instead of having to react to changes
dynamically. In NixOS these things are usually already taken care of
during stage 1 (early ramdisk) if you use them.
currently, only support for fully disabling nvidia is provided, which
is helpful for saving power/heat.
In the future, this should be extended so we can choose:
- nvidia only (choose between nouveau/nvidia driver)
- IGP only
- Hybrid (choose between nouveau/nvidia driver, use the "bumblebee" package/daemon)
