the sda1 fstab:
/dev/sda1 / ext4 errors=remount-ro 0 1 /dev/sda3 /home ext4 defaults 0 2 /dev/sda2 none swap sw 0 0 UUID=8C5E-D456 /boot/efi vfat defaults 0 1
the sdc1 fstab: LABEL=BOOT / ext4 errors=remount-ro 0 1 LABEL=HOME /home ext4 defaults 0 2 LABEL=swap none swap sw 0 0 UUID=8C5E-D456 /boot/efi vfat defaults 0 1
The labels point to the same debvices/partitions except for the first one -- LABEL=BOOT is /dev/sdc1 -- and the swap, which are on sda2 and sdc2 respectively. (sda1 has the label BOOT-HD, fwiw.)
I'd like to see:
lsblk -f grep GRUB_DISTRIBUTOR= (on/from both sda1 and sdc1) grep GRUB_DISABLE_OS_PROBER= (on/from both sda1 and sdc1) tree -D /boot/efi/ (on/from both sda1 and sdc1) efibootmgr -v
