I installed arch Linux but I forgot to make my desired home partition. /home. I accidentally forgot to change the partition from Linux filesystem to add /home. I changed the partition to /home after installation and setup of Gnome. I want to make it auto mount by use of uuid. All my drives are GPT. I've had to do this in Ubuntu before but when I changed Swap size. I no longer remember how I did that and this is my first installation of Arch. I have set up two drives for my system. A 120GB SSD as well as a 1TB HDD.
My partitions are as follows:
SSD 120GB /dev/sda1 524MB BIOS Boot
/dev/sda2 472MB Linux Filesystem Ext2
/dev/sda3 119GB Linux filesystem Ext4 / (root)
HDD 1TB /dev/sdb1 989 GB Ext4 /home /dev/sdb2 11GB SWAP
Any help would be greatly appreciated.
