5984246f96 Loader: support booting OS from memory disk (MD)
Until now, the boot image can be embedded into the loader with
/sys/tools/embed_mfs.sh, and memory disk (MD) is already supported
in loader source. But due to memory disk (MD) driver isn't registered
to the loader yet, the boot image can't be boot from embedded memory
disk.

42cd37dfbd gptboot.efi: Add man page
Add a man page for gptboot.efi. Describe when and how to use this as it differs
from the BIOS cases. Include cross reference for the preferred method described
in efibootmgr(8) as well as cross links in both gptboot(8) and gptboot.efi(8) to
the other.

This man page was heavily copied from the gptboot.8 man page by Warren Block.
They are different enough to need separate man pages for clarity, but there's
enough similarity that I worry about the duplication. In the really long term,
gptboot(8) will disappear, so having the same info here will help when that
day comes. In the short to medium term, the information is likely to not
change in gptboot(8) and any changes to gptboot.efi(8) will be easier to
make in a separate copy.

loader.efi(8) needs a complete rewrite from scratch, otherwise I'd have
referenced gptboot.efi(8) from there.

335fe94f90 Add init_exec kenv(1) variable, to make init(8) execute a file
after opening the console, replacing init as PID 1.

From the user point of view, it makes it possible to run eg the
shell as PID 1, using 'set init_exec=/bin/sh' at the loader(8)
prompt.

1ddc8a8e68 Follow up to r336919 and r336921: s/efi.rt_disabled/efi.rt.disabled/
The latter matches the rest of the tree better [0]. The UPDATING entry has
been updated to reflect this, and the new tunable is now documented in
loader(8) [1].

408c1ff8f4 Clarify that boot_mute / boot -m mutes kernel console only
Perhaps RB_MUTE could mute user startup (rc) output as well, but right
now it mutes only kernel console output, so make the documentation match
reality.
