I need to do a EFI network (boot and) install, and I'm wondering if this
file (bootnetx64.efi) can help me. But there is no documentation on it
(except the suggestion in the install manual
https://www.debian.org/releases/stable/amd64/ch04s05.en.html#dhcpd
"specify a boot loader appropriate for UEFI machines, for example...")
My problem is this: I can UEFI netboot using grubx64.efi. However, it
loads a standard grub.cfg which runs an interactive installer. I need
to preseed the install, and I need to load a different preseed file for
each server booted.
For non-uefi this is achieved using pxelinux's behaviour of tftp-ing a
configuration based on MAC addresses etc. and fallback to a standard
location.
I'm wondering if grubx64.efi or bootnetx64.efi support similar
behaviour? Or else how to get specific information into the installer
(such as IP address and hostname), if not via specific pre-seed files
per machine?
(We can overwrite the grub.cfg each time with the needs of a specific
server, but this is not ideal, as it will cause a failure if more than
one machine is being net-installed at the same time.)
In general though I'm also looking for pointers to documentation. If
someone could point to anything that explains what bootnetx64.efi is and
what it does, I'd be happy to contribute that back to the wiki or
install manual.

P.S.
I didn't find much relevant in the install manual except as mentioned above.
I didn't find bootnetx64.efi not mentioned in any of the following
locations:
* https://wiki.debian.org/DebianInstaller/FAQ
* /usr/share/doc/debian-installer-12-netboot-amd64, or any man pages in
the package
* https://wiki.debian.org/DebianInstaller
* https://wiki.debian.org/SecureBoot
* https://wiki.debian.org/UEFI
*
https://duckduckgo.com/?q=bootnetx64.efi+debian+network+boot+uefi&t=ftsa&ia=web
https://wiki.debian.org/PXEBootInstall mentions using grubx64.efi for
the standard installer, but doesn't mention how to select a grub.cfg per
machine.
