>From the kernel config instructions (something not written by the systemd >devs): This option enables / disables the invocation of user-helper (e.g. udev) for loading firmware files as a fallback after the direct file loading in kernel fails. The user-mode helper is no longer required unless you have a special firmware file that resides in a non-standard path. Moreover, the udev support has been deprecated upstream. Announcing a feature as deprecated and later dropping it is hardly controversial. You chose a distro that gives you a choice of things like your udev implementation and your kernel implementation (or using udev at all), and as a result you get to deal with the fact that some versions of the one have constraints on how you use the other. If you ran a distro like Ubuntu you wouldn't have to worry about any of this, as you'd use the udev they gave you and the precompiled kernel they gave you and the world's greatest desktop environment and you'd be happy with it. Anybody who has run Gentoo for a long time knows that from time to time some change comes along and you'll just have to deal with it - you can't just ignore things like firmware-loading on Gentoo the way you can with some other distros. Of course, nothing prevents anybody from creating a preconfigured kernel for Gentoo. There is genkernel of course, though I think we probably could do better. Most seem to be happy just managing their own kernel configurations, and I think that is why nobody has bothered to spend much time perfecting a canned kernel. Going back to the original question, yes - it is that simple. Dependencies are just dependencies - you only have to worry about them when you turn things ON. -- Rich
