As intended, the kernel parameter being passed to linux is
"root=/dev/sda1". The "search --no-floppy --fs-uuid --set
1120cb0b-5fb5-4b1c-9239-da1660c90ebd" is used by *grub*  to find the
filesystem containing the kernel/initramfs to load them.
GRUB_DISABLE_LINUX_UUID=true is intended to be used to allow booting
kernel's whose initramfs cannot handle UUIDs. Since UUIDs are
generally more reliable, and grub can always use them, grub itself
always does use them to find the kernel/initramfs.
