Of course. PXElinux is a Linux Boot loader. Loading vmlinuz (the Linux
Kernel file, I suppose?) is its job. Since the Kernel file is loaded via
~ TFTP over the network, it has to exist in the tftpboot directory.

Nope. vmlinuz is read only by the boot loader, only once per boot. You
don't need the file again later (so it does not need to be in your
initrd)...

Wrong. PXELINUX, as I wrote, loads the kernel file via TFTP and
uncompresses it into RAM. Afterwards it loads the initrd file and puts
it into Memory too. (Don't know if it's decompressed by PXELINUX or by
the Kernel itself, but that doesn't matter here).

HTH
