This has surely been asked before, but searching turned up nothing. Is there a recommended way to resume an interrupted system build? I run on very old and slow machines. I haven't completed a full system build yet, but on my main system (Intel Celeron single core 2GB RAM from 2003) 8 hours didn't get me very far. A fresh kernel build takes about 90 minutes on that machine.
"make build" does a complete clean of the build tree from what I can tell by looking at the Makefile. It would be nice to pick up where I left off in case a power failure or my own stupidity interrupts a build.
