Live image doesn't boot when EVE-OS is installed on another storage device

[rene]

Description

Currently we use the same IDs when generating disk images. This approach causes some problems, especially on ARM devices, when we have EVE installed on eMMC and we want to run a live image (for testing) from the SD Card. In this case, the partition on eMMC will be detected first than the partition in the SD Card (or USB stick) and will be considered as the rootfs.

How to reproduce

It applies to all EVE versions:

• Install EVE-OS to some storage device (eMMC, NVMe) that is listed before SD Card or USB stick
• Create a live image and try to boot from SD Card, USB stick

The partitions from the installed device (eMMC, NVMe) will be detected first and mounted instead of the partitions in the SD Card/USB Stick. This will confuse EVE and make it to reboot.

How to solve this issue?

We must implement dynamic UUID generation for disk partitions.
