run raspiblitz on single hdd/sdd

[Schnitzel]

I'm trying to run raspiblitz on a linux notebook with 1TB internal SSD. I partitioned the SSD this way:

nvme0n1     259:0    0 953.9G  0 disk
├─nvme0n1p1 259:1    0   512M  0 part /boot/efi
├─nvme0n1p2 259:2    0  93.1G  0 part /
├─nvme0n1p3 259:3    0   977M  0 part [SWAP]
└─nvme0n1p4 259:4    0 859.3G  0 part 

I'm running into issues where the install script doesn't like to use the nvme0n1p4 as the datadisk, as then the boot and OS disk and the data disk all have the same parent disk and then this check in the setup script prevents this:

So I was wondering if there is any trick to run raspi on a single SSD. I'm aware that this might cause possible problems in the future and upgrading a raspiblitz might be a bit complex, but I feel for experts in linux this should not be too hard.

I did try to mount /dev/nvme0n1p4/ to /mnt/hdd but then the raspiblitz.conf is never configured and a lot of other stuff doesn't work, so I feel this is not really a good solution.
