I just want to unionfs 2 drives together

Question

I would like to run the following code automatically without me having to do anything:
sudo unionfs -o cow -o allow_other /media/Media/Vids/Secondary=rw:/media/Media/Vids/Primary=rw /media/Combined
sudo unionfs -o cow -o allow_other /media/Combined=rw:/media/Media/Vids/Local=rw /media/Vids
However I keep running into pitfalls
I tried to do a system command file launched with a .service file
the bash file resides at /usr/bin/unionfsscript
#!/bin/sh
unionfs -o cow -o allow_other /media/Media/Vids/Secondary=rw:/media/Media/Vids/Primary=rw /media/Combined
unionfs -o cow -o allow_other /media/Combined=rw:/media/Media/Vids/Local=rw /media/Vids
which I did a chmod +x afterwards to the file
Then I wrote /etc/systemd/system/unionfsservice.service
[Unit]
Description=Load All Network Drives
[Service]
Type=oneshot
ExecStart=/usr/bin/unionfsscript
[Install]
WantedBy=multi-user.target
Afterwhich I ran systemctl enable unionfsservice.service
Then I ran systemctl start unionfsservice.service
-Did nothing
Afterwhich I ran:
systemctl status unionfsservice.service
and got:
unionfsservice.service - Load All Network Drives
          Loaded: loaded (/etc/systemd/system/unionfsservice.service; enabled)

I tried running the /usr/bin file as a startup script.........even tried putting sudo in the file - NOTHING IS WORKING
I tried doing a /etc/fstab with the following
unionfs  /media/Combined unionfs dirs=/media/Media/Vids/Primary=rw:/media/Media/Vids/Secondary=rw -o allow_other    0 0
which kind of worked.....it would mount the drive but I couldn't view the contents unless I did sudo /media/Comined in a terminal. and if I put allow_other right after the 2nd unionfs it made no difference, I can't use a -o flag either.
Any ideas I am going crazy over this...I just want to merge the folders together into one folder when the pc boots up
I was able to do so in a rc.local file....but since Arch moved to a forsaken systemd structure (which is a horrible idea in my opinion) that idea has been crushed.
any help please

Answer 1

Well, with the fstab part. /etc/fstab is run as root, so all the dir's will be owned by root by defualt.
You would need to add like these to the mount options in fstab
uid=1000,gid=100
Like here is my Downloads directory fstab entry that I mount as a tempfs
tmpfs /home/user/Downloads tmpfs rw,nodev,noatime,noexec,nosuid,uid=1000,gid=100,mode=700,size=10G 0 0
