Comment 22 for bug 704763

I ran into this problem under Ubuntu 20.04 Beta on my 2008 MacPro while attempting to have the boot loader installed on the same drive as the linux installation rather than the drive with my macOS installation. Using the Custom Partitioning option to install / on /dev/sde2 (ext4) and the device for the boot loader installation set to /dev/sde, the following glitch occurred. The boot loader was still erroneously installed on the EFI partition of the macOS drive (/dev/sda1) and worse the installer recreated the EFI partition on /dev/sde1 with the identical blkid name as that used by /dev/sda1. So it left my system with two physical drives having identical blkids for separate partitions.
