The kernel developers insist that the kernal assigned /dev/sdx names are not to be considered persistent even for a constant hardware configuration. Although it certainly is unusual for internal SATA drives to change between boots (BIOS behavior?) it is not guaranteed that such names won't ever change between boots. So, reference the drives using their PARTUUID. The kernel understands this referencing method natively and will not require any initramfs. You can see the PARTUUID of all the drives via: lsblk -o NAME,FSTYPE,PARTUUID e.g., 7b01c1ac-a7b2-4841-a36d-3a7eb46ed741 For the kernel command line and grub, the format to reference by PARTUUID is: root=PARTUUID=7b01c1ac-a7b2-4841-a36d-3a7eb46ed741 https://wiki.gentoo.org/wiki/GRUB For fstab it is formatted like: PARTUUID=7b01c1ac-a7b2-4841-a36d-3a7eb46ed741 / ext2 defaults 1 1 You will have to have a gdisk-created partition table for each partition to be assigned a PARTUUID. Note that you cannot use UUID at boot without an initramfs - as UUID's are post-udev assigned things and will not be available to the kernel during the initial boot process.
