    Hi!
    Is it just me or they swapped again? (an unexpected electrical
    shutdown gave me further head-scratching)

    Thanks,

    Are you using e.g. "/dev/sda1" in your grub configuration and fstab?

    Using UUIDs or block labels on your disks/partitions works around any randomness in the order in which the kernel sees devices.

    e.g.
    '''
    menuentry 'Linux' {
    echo 'Loading Linux ...'
    search --no-floppy --label --set=root frodoboot
    linux /vmlinuz root=LABEL=frodoroot ro
    initrd /initramfs.img
    }
    '''
    '''
    # blkid /dev/sda1
    /dev/sda1: LABEL="frodoboot" UUID="a779e4cf-405e-4e03-a272-e714ba17cd18" BLOCK_SIZE="1024" TYPE="ext4" PARTUUID="de7c8912-01"
    '''
