can't get a full fbsd 7.2 amd64 install

[Len Conrad]

fbsd 7.2
amd64
"kernel developer" install

Here's a successful install du

du -d1 -h /
2.0K    /.snap
2.0K    /dev
1.8G    /usr
1.6G    /var
1.7M    /etc
2.0K    /cdrom
2.0K    /dist
1.1M    /bin
206M    /boot
6.7M    /lib
396K    /libexec
2.0K    /media
2.0K    /mnt
2.0K    /proc
4.0M    /rescue
 42K    /root
4.3M    /sbin
 24K    /tmp
3.6G    /  <<<<<<<<<<<<<

here's what we're getting on another machine, way too little:

du -h -d1 /
2.0K    /.snap
2.0K    /dev
1.1G    /usr
238K    /var
1.7M    /etc
2.0K    /cdrom
2.0K    /dist
1.1M    /bin
411M    /boot
6.7M    /lib
396K    /libexec
2.0K    /media
2.0K    /mnt
2.0K    /proc
4.0M    /rescue
 10K    /root
4.3M    /sbin
 12K    /tmp
1.5G    /     <<<<<<<<<<<<<

and /usr is also missing 800 MB just after install.

using 7.2 amd64 disc01, as forever.

I ran sysinstall, post install config, and checked stuff, but still didn't get, eg, anything in /usr/bin/

comments?

Could my client have chosen the wrong .iso?
