I was wondering if it is possible to disable initramfs on an ext4 partition in order to reduce the time it takes Ubuntu (12.04) to boot. See source here!

Instead, setting up the root device directly to sda1 (in my case) and adding a parameter about the correct filesystem type to use, may cause the kernel to boot the system without initramfs and a few seconds faster. Is this correct?

Unfortunately I do not know where to put this lines in Ubuntu:

linux /vmlinuz-3.2.0-35.x86_64 root=/dev/sda1 rootfstype=ext4 quiet
#     initrd /initramfs-3.2.0-35.x86_64.img
