I have no idea. after the installation all was normal, besides that i had to
partitions with btrfs. i often looked at hat usage of the root partition, it
always was 130 gb, one day i saw 170 gb, then i found out, that it was the two
partitions together. 

But the strange thing is, grub2 changed too. 

it was:
opensuse leap 15 
opensuse leap 15 advanced
and something with snapshots

after:
opensuse leap 15 
opensuse leap 15 advanced
opensuse leap 15 (on /dev/sda2
opensuse leap 15 (on /dev/sda2 advanced

and under advanced there has been 4 entrys the tow latest kernels each with the
recovery mode, now the recovery mode disappered. I don�t know what happend,
maybe an update? but i can�t remember when the change occurs, there wasn�t a
critical update like kernel or nvidia.
