/etc/fstab reads filesystem labels and ignores partition names.
file browsers read partition labels, so were using FUNTOO for the root drive so our branding is correct in file browsers.

Come back at DONE! to have the legacy chicken lay the uEFI egg.

At this point you have legacy mode grub installed & also x86_64 uEfi installed from a legacy boot.
 
 
More experimental garbage:
i386 efi doesn't insert correctly.  let's try bootloader id = "FUNTOO"

/etc/fstab label grabs the file system label, not the drive name. 
you should be able to name the root drive funtoo, and have it show up as that in other operating systems when the usb is inserted.

Backwards Compatible Partition Table

List the device to be partitioned, mine is on /dev/sdc 

root # lsblk -o name,size,label,partlabel
root # cgdisk /dev/sdc
Command: o ↵
This option deletes all partitions and creates a new protective MBR.
Proceed? (Y/N): y ↵
Command: n ↵
Partition Number: 1 ↵
First sector: ↵
Last sector: +1M ↵
Hex Code: EF02 ↵
Command: c ↵
Partition number: 1
Enter name: BIOS Boot
Command: n ↵
Partition Number: 2 ↵

Last sector: +128M ↵
Hex Code: EF00 ↵

Partition number: 2
Enter name: BOOT
Command: n ↵
Partition Number: 3 ↵

Last sector: ↵
Hex Code:  ↵

Enter name: FUNTOO
Command: w ↵
Do you want to proceed? (Y/N): Y ↵
root # mkfs.vfat -F 32 /dev/sdc2
root # fatlabel /dev/sdc2 "BOOT"
   Tip

jfs is amazingly fast, use it!

https://www.phoronix.com/scan.php?page=article&item=9way_linux317_fs&num=2 

root # mkfs.jfs /dev/sdc3
root # jfs_tune -L "FUNTOO" /dev/sdc3
root # mount /dev/sdc3 /mnt/funtoo
root # mkdir /mnt/funtoo/boot
root # mount /dev/sdc2 /mnt/funtoo/boot

STOP HERE!!! go back to Undead_USB_Install now and start from the top code block.

experimental garbage

root # grub-install --target=x86_64-efi --bootloader-id="FUNTOO" /boot/efi
root # grub-install --target=i386-efi /boot/efi

gparted

gparted isn't granular enough to make bios boot partitions to load legacy mode in GPT. if theres a easy way to do this i didn't see it. cgdisk it is.... Device > create partition table > GPT

/dev/sdc1 name: "BOOT Bios" size: 1MiB flags: bios_grub

/dev/sdc2 name: "BOOT" file system: fat32 label: BOOT size: 128MiB flags: boot, esp

/dev/sdc3 name: "funtoo" file system: jfs label: ROOT size: 14.9GiB


egoless grub config generation

edit /etc/grub.d/10_linux to make it pickup the initrd.... 

          "initramfs-debian-sources-${version}" \
          "initramfs-debian-sources-lts-${version}" \

grub-mkconfig -o /boot/grub/grub.cfg
