That's a debian-specific thing...

Y= ep and he is running Ubuntu which is a derivative of Debian ? His .config j= ust told me this :-)
But valid point will keep things generi= c in future.
CONFIG_CC_VERSION_TEXT=3D"gcc (Ubuntu 9.3.0= -17ubuntu1~20.04) 9.3.0"

That's not what I said.

What I *said* was "if you're a newbie who's all "ZOMG I&#= 39;m going to accidentally break it"
maybe you shouldn't be a kernel hacker. :)

So he breaks it. Then comes the fun part when he lear= ns how to fix it :-)

Oh, there's people like Greg KH who know a lot more than I do.=C2=A0 He= 's also
*paid* to know a lot more than I do. :) After 4 decades in IT, I've jus= t gotten
good at debugging and knowing where to start checking for more data on
something.

Why don't any of us ever get paid ? Ouch...
