/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: "ROOT" file system: jfs label: ROOT size: 14.9GiB
/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.
==undead really targets USB, SSD, and NVME.  Swapping is best handled in a file or turned off.==
https://www.funtoo.org/Talk:Install/GPT_Partitioning <--correct partitioning to load legacy mode, and uefi mode.
{{console|body=
###i## mkfs.vfat -F 32 /dev/sdc2
###i## mkfs.jfs /dev/sdc3}}
label your partitions.
{{console|body=
###i## mlabel -i /dev/sdc2 ::"BOOT"
###i## jfs_tune -L "ROOT" /dev/sdc3
}}
{{console|body=
###i## mount /dev/sdc3 /mnt/funtoo
###i## mkdir /mnt/funtoo/boot
###i## mount /dev/sdc2 /mnt/funtoo/boot
}}
STOP HERE!!!  go back to [[Undead_USB_Install]] now and start from the top.
(minimal tarball to speed up reinstalls to build documentation)
{{console|body=
###i## cd /mnt/funtoo
###i## wget https://build.funtoo.org/1.4-release-std/x86-64bit/generic_64/stage3-latest.tar.xz
###i## tar --numeric-owner -xpf *stage* && rm -f *stage*}}
Show partition labels.
{{console|body=
###i## lsblk -o name,label
}}
stab 2 at getting uefi going from legacy machine.
{{console|body=
###i## mkdir /boot/efi
###i## mount /dev/sdc1 /boot/efi
###i## grub-install --target=x86_64-efi /boot/efi}}
/boot/efi/efi/gentoo/grubx64.efi is generated.  doesn't load probably secure boot unsigned image or something like that.
stab 3
gpt partitioning via official install method gdisk.
testing legacy grub + gpt to verify that MBR can be deprecated.
legacy loaded grub this time from a gpt partition.  i think i didn't delete the fstab defaults, it wasn't mounting root correctly but very close to running.
