I have two objections to your proposal above. 1) You're telling other=20
folks how to spend their time. If someone wants to add this, what really=20
is wrong with it, other than you would have wanted something else? It's=20
not like we're adding a feature that lets a user gain root privs or=20
something silly like that; I fail to see how it will really hurt.
2) You're assuming that adding a sysctl to get a string is as hard/easy as=
adding sysctl interfaces for a program to get data. I believe they are=20
not. I personally feel quite confident that I can add a sysctl to expose a=
string or int already in the kernel. I am not at all confident I can add=20
the data marshaling needed to replace a kvm groveler.
I'm not disagreeing that it'd be nice to get rid of kvm-groveling, I in=20
fact think it'd be good. I however think we should not tell folks to NOT=20
add features because they didn't remove kvm groveling.
