**erlangen:~ #**
The EFI System Partition nvme0n1p1 is shared by two System partitions. nvme0n1p2 holds the main system and nvme0n1p3 a rescue system:
**erlangen:~ #** **efibootmgr**
BootCurrent: 0000
Timeout: 1 seconds
BootOrder: 0000,0002,0001
Boot0000* tumbleweed
Boot0001* tumbleweed-rescue
Boot0002* UEFI OS
**erlangen:~ #**
Grub Multiboot Configuration:
By default both the main system and the rescue system will overwrite their bootloaders, which can be annoying. Users may want to have them independent of each other. Assign unique values to GRUB_DISTRIBUTOR:
**erlangen:~ #** grep GRUB_DISTRIBUTOR /etc/default/grub
**GRUB_DISTRIBUTOR**=Tumbleweed
**erlangen:~ #**
