[SOLVED] boot partition does not output on genfstab.

Question

I have installed Arch Linux 5 or 6 times and even had desktop environments. This is a first for this to happen. I do not have a way to copy and paste so I cannot reproduce all code.
I have 4 partitions. They are:  /, home, boot, and swap. This is new for me and I am a bit confused. I did a search and found this, but no luck for me.
https://bbs.archlinux.org/viewtopic.php?id=118114
Unfortunately, this is not helping me, or I just do not see it.
The root, the home and the swap partition output normally. It looks like this:
# /dev/sda2
UUID=**************************** / ext4 rw,relatime,data=ordered 0 1
# /dev/sda4
UUID=**************************** /home ext4 rw,relatime,data=ordered 0 2
# /dev/sda3
UUID=**************************** none swap defauults 0 0
The boot partition is just not there. So i did this:
lsblk -f | grep sda1
and appended the UUID from this output to the fstab and made a new fstab listing.
The boot partion of fstab reads:
# /dev/sda1
UUID=lots_of_alpha_numbers /boot ext4
My questions:
How do I know what options to add for the boot partition?
Why would cause this not to show up?
What options do I put for /boot - the same as / and /home (rq,relatime,data=ordered)?
What order should the /boot partion load? All other installs it did root as 1, home as 2 and boot as 2.
I have installed Arch Linux successfully at least 5 times and never had this issue. So I am wondering If manually adding this is covering up a bigger problem.

I want to make clear what happened. Because I made the same mistake again, it dawned on me what is happeneing.. I went back to the wiki and found that it was there all along.
After creating the partitons I made 2 directories.
# mkdir -p /mnt/boot
# mkdir -p /mnt/home
And here is where MY mistake was...
# mount /dev/sda1 /mnt/boot
# mount /dev/sda4 /mnt/home
# mount /dev/sda2 /mnt
What happened,  because of the ORDER that I mounted, the mount points of /mnt/boot and /mnt/home were comprimized and because they are subdirectories of /mnt. I got careless because I was getting good at installing Arch without the wiki and because I did not understand a fundemental of the system it was messed up.
I went back after I figured out my problem and saw that the mount and partitons wiki was useful and would have prevented if I was a bit more observent.
It clearly states: "The / (root) partition must be mounted first: this is because any directories such as /boot or /home that have separate partitions will have to be created in the root file system. The /mnt directory of the live system will be used to mount the root partition, and consequently all the other partitions will stem from there. If the root partition's name is sdxR, do: 
This was a good learning experience for me.
