GhostBSD ARM64 porting from x86 code base (RISC-V in the future??)

NetBSD aarch64 10.0  install on Raspberry Pi 4B,   wahoo it works, Fred!  Well, this is a good accomplishment for May 7th 2024. Installing NetBSD 10.0 on a Raspberry Pi 4B with 8Gigs.     May 7th is also my son Conner Louis Tilley:    7lbs, 7 ounces, born on the 7th of May.  My little triple 7 ( in the next month June of 1995 Boeing announced the Triple Seven, 777 model Dreamliner Airplane ) arrived into my Life,  my son,  Connor Louis Tilley. https://www.facebook.com/connor.tilley.2903   He is a video games developer with Amazon Games When did the Boeing Triple Seven, 777 come out? The Boeing 777 is a family of wide-body twin-engine commercial jet aircraft with variants for both passenger and cargo transportation. The 777 was first flown on June 12, 1994, and commercial service commenced on June 7, 1995. So there are 2 objectives to accomplish when setting up NetBSD 10.0 for a Raspberry Pi 4B.   Download and  write  arm64.img into a USB Flash drive stick.  Download Paul Bartard's

 PXE aarch64 TFTp boot a Raspberry Pi 4B over the network, May 5 2024   PXE:TFTPd Setup   This is one of the easiest pieces to get working. mkdir /tftpboot .  zfs list; zfs create -o compress=off arm64pool/tftpboot Uncomment the tftp line in /etc/inetd.conf . tftp    dgram   udp     wait    root    /usr/libexec/tftpd      tftpd -l -s /tftpboot # enable the ftp server ftp    stream  tcp     nowait  root    /usr/libexec/ftpd       ftpd -l Add inetd_enable="YES" to your /etc/rc.conf. Run /etc/rc.d/inetd start . Now that the server is working, we need the boot loader that will be served via TFTP to the PXE loader on your machine. for x86_64, maybe for aarch64 needs a different pxeboot file and file name?? cp /sys/boot/i386/pxeldr/pxeboot /tftpboot  zfs create  example root@Ghost14-selfbuilt-rpi4B-nginx-tst1:~ # zfs create -P -o quota=5G -o mountpoint=/tftpboot arm64pool/tftpboot create    arm64pool/tftpboot property    quota    5G property    mountpoint    /tftpboot zfs set com
