Hello, Gentoo.
Having just built linux-4.14.7-gentoo, suddenly a new version of the
kernel, linux-4.14.8-gentoo-r1 has become stable. Configuring a
kernel from scratch is a repetitive drudge.
There is some way of initialising a new kernel .config from an
existing one, I am sure, but I can't find it. I've looked at the
Gentoo wiki, I've looked at (some of) the kernel's own
documentation. The nearest I can find is make oldconfig, which
supposedly does what I want, but it just seems to start off with a
default .config and go through the hundreds of questions one at a
time.
So, would some kind soul please tell me how to get my old .config
into a new one properly. Thanks!
You need to copy your old .config into the new kernel source
directory. "make oldconfig" then uses those values, and only asks you
about new items. It sounds like it was asking about everything because
it didn't have the old file as a starting point - so was starting from
scratch.
