From: Martin Jansa Are you sure that you're not building some unnecessary IMAGE_FSTYPES? No, I'm not sure. Last time someone asked my why it takes so long I've added some debug output to do_rootfs and found out that only half of the time was opkg installing packages and the rest was

I got really tired of waiting for builds on my lowly dual-core Atom machine, so I went out and bought a nice fast machine with an i7-4770K and a Samsung SSD. Full builds are now screechingly fast, over 10x compared to the Atom. But when making a tiny change, I still have to wait for do_rootfs.
