I am configuring a Linux kernel before I compile the code. However, after I was thirty minutes into answering the many questions concerning various kernel settings, I accidentally pressed Ctrl+C. I do not want to start over, so is it possible to make the configuration tool resume where I left off?
You probably want to adjust the workflow a little bit, since configuring the Linux kernel from scratch is not for everyone (I'd almost say it's not for anybody). First, you are much better of with menu-based configurators like
make menuconfig or the GUI based ones, as it usually allows you to save the configuration when you deem that a good idea. Second, unless you are really savvy about kernel things, you want to use some basic configuration as a starting point - either
make defconfig or use your distribution as a base for your endeavours.
make help will tell you all the build targets (including the configuration ones, of which there is about dozen and a half) and the applicable options.
