Phoronix: There Is Finally Work To Allow Sysctl Parameters To Be Set From The Linux Kernel Command

File this under the "I can't believe it took this long" or "why wasn't this done before" section... Thanks to SUSE, there are finally patches pending to allow easily setting sysctl parameters from the kernel command line using a generic infrastructure...

I file this under the "why would I ever need that" section, I can already do that either temporarily or permanently, easily.

There is nothing wrong with having more options.

Or you know, just not for the end-user. It may be an easier set-up for others or not, either way it will be valuated.

I'm surprised this wasn't a thing.

actually there is.

More options => more code => more clutter => more problems!

Well, it's dead easy to do in an initramfs, you would not see any difference. And the mere existence of an initramfs is to get code like that out of the kernel.

Having this in the initramfs has other advantages, like bering able to load the necessary modules first so that your sysctl paths actually exist and the setting via cmdline works.
So the in-kernel mechanism can only work for builtin modules, for the rest you would need an initramfs (with the additional modules to load). Sounds like rather useless to me.

This seems to be the major break for innovation.

you have to find a balance between the cost of maintaining a feature and the advantages it provides.

not sure about the sysctl at boot thing, tough

[Buntolo]

When can I find a list of available sysctl commands for kernel?
