Yes. The list of disks shown in the partitioner is currently:
RAID device #1
RAID device #2
/dev/nvme0n1
/dev/nvme1n1
SCSI2 (0,0,0) (sda) - the USB stick I booted from
SCSI1 (0,0,0) (sdb) - the first storage drive
... the other seven storage drives ...

Partitioning is identical on both nvme drives, consisting of:
1.0 MB free space
2.0 GB ESP (bootable)
8.0 GB swap
1.9 TB RAID physical device
331.8 kB free space

RAID Device #1 is 1.9 TB, ext4fs, and set to mount on /
RAID Device #2 is 2.0 GB, ESP, and bootable

...and this is where it dies. I'm now in the text-mode "expert
install", and there is no option to manually specify a partition to
install GRUB on, only a yes/no "Force GRUB installation to the EFI
removable media path?" prompt. Regardless of which answer I choose, I
get "Unable to install GRUB in dummy" and syslog records "failed to get
canonical path of /dev/md2".
I also tried dropping to a shell and manually running `grub-installer
/dev/nvme0n1` and got the error "ls: /dev/nvme0n1/proc: Not a directory"
Manually running grub-installer for /dev/md2 and /dev/nvme1n1
(unsurprisingly) produced similar results.
