waiting for checking for initramfs, SLOW boot

hey everyone

I have created an embedded system that I need to make boot up as quickly as possible. It of course takes a long time to uncompress the root filesystem, which I will have to deal with unless I can find more ways to make the system smaller. However, on thing that I believe I can get rid of that causes the boot time to take forever is where it says something about "checking if image is initramfs...." which takes a while, and then comes back and says that it isn't, and then continues booting. Anyone know how I can skip over this?

Speed and space considerations suggest all necessary drivers be compiled into the kernel, so maybe you do not need an initrd (initial ramdisk). Looking at the kernel code (init/initramfs.c) it looks like this check only gets done if CONFIG_BLK_DEV_INITRD is defined, so if you turn this off in the kernel config you should be OK. You could always hack the code directly to bypass the check of course (I'm looking at v2.6.7)

To save more space/time have a look at
