For sure!

But as I don't know, which of it causes the trouble, I told you the whole 

To me it appears, that grub-install changes a pointer in mbr and on reboot, 
grub looks like it does not find the target of that pointer. So it hangs in 
boot screen.

But I can't state, whether grub-install puts a wrong pointer into mbr or 
whether the drive order changed on reboot and grub is not able to resolve the 
target of that pointer. One of the three causes troubles.

So if you have any hints/testcases - I'm willing to test, but I don't by 
myself what to do to locate the error.

The short answer is - I use both labels and uuid, depending whether I wonna 
refer to a physical or logical partition. I use labels for the logical ones.

The major difference between the "old" and "new" partition: 
The old system uses separate drives for /usr and /var - the new one uses all 
in one partition.
The minor difference:
The old system is a complete GUI installation, the new one only basic system.
