On a 4GB system with /tmp as tmpfs I only have an 1MB sized /tmp now. Which breaks a lot of stuff, including the scripts to install new kernels. When I remount it manually with a larger size things works again. I haven't tried to bisect or debug it, but I'm reasonably sure the problem wasn't there with 4.3. -Andi -- ak@linux.intel.com -- Speaking for myself only.
