Progress! But not quite there yet.
It occured to me that the Samsung drive might have been
corrupted at
some point, so I dd'd /dev/zero into the first few gigabytes of
the
drive to completely wipe the partition table. Sure enough, it
showed up
on the partitioning stage of the graphical installer and I was
able get
all the way through to the end... except for the same
efibootmgr error.
Ok! So it seems that the additional patch is improving the
situation. I
also fear that 1.1.0-rc2 is having the same error as 1.0.1 but
is
swallowing it. I will investigate it further.
Regarding the efibootmgr error, I'm not really familiar with
EFI. Can
you check that efivarfs is mounted as suggested here[1]?

Followed the advice on the SE answer, specifically:
$ mount -t efivarfs efivarfs /sys/firmware/efi/efivars
$ rm /sys/firmware/efi/efivars/dump-*
And it successfully installed!.. sort of.
Guix now boots to this screen[1] and then hard freezes.
Just in case its relevant, I did the installation twice (both
through
TTY in order to run the mount/rm commands):
1. 2 partitions, boot and encrypted root w/ swapfile, using
desktop.scm
as a base
2. 3 partitions, boot, root, and a swap partition, using
lightweight-desktop.scm as a base
Both had the same results.
