Where does Pi get the PARTUUID's from and how can I change the /home partition to use the one that follows the model of the first 2 partitions?
PARTUUID is a value derived from the PTUUID (Partition Table UUID, also known as the Disk Signature or DiskID).
PTUUID is a 32-bit (4 bytes) value (typically randomly generated when the MBR is created but can be changed later if desired) stored at offset 0x1B8 in the MBR (Master Boot Record).
A PARTUUID is derived from the PTUUID by appending the partition number. For example, if the PTUUID is 1234CDEF, PARTUUID's will be:
Partition #1 : 1234CDEF-01
Partition #2 : 1234CDEF-02
Partition #3 : 1234CDEF-03
If the PTUUID is changed, all PARTUUID's will obviously change, requiring references to them in cmdline.txt and fstab to updated accordingly.
