Only to add that this is because of Linux and the way it is doing
things. If i would use FreeBSD on bare metal, then i would have
an EFI boot loader on EFI that knows (only) enough to ask for
passphrase (correct me if i am wrong), and can then boot the
kernel from FFS or ZFS. (You have to choose dedicated ZFS boot
loader iirc, but despite that...)
I know GRUB (and maybe other) Linux bootloaders can do all that,
but they are huge, are badly maintained, or under-documented, let
alone with local manuals, and i am too stupid to configure them
(due to all that). refind is ok, however. But.. be aware of
typos in the configuration..
But anyhow. With an EFI_STUB Linux kernel i can save me all that,
with busybox i get a complete environment (i then even create an
initrd in /boot/ on the fly so i do not have to type the password
a second time, that can (optionally) be cached, and is, actually
-rw------- 1 root root 4495987 May 29 16:29 .kent.initrd.0
Unfortunately cryptsetup is needed even though, i think, the
kernel has anything needed; you just cannot access it. cryptsetup
is only needed for "$cs open $PART_ROOT p_root --key-file -".
Of course i am no real Linux expert but only a do-it-yourself guy.
busybox allows me to manage this easily, to answer your question.
