There's another (potentially large) problem: If you need to add packages
to the distribution, and the target of the build is not the same as the
machine you're building on then the pkg add command in the handbook fails.

root at NewFS:/pics/CrossBuild/embedded/rpi2 # more _.cust.install_packages
+ install_packages
+ mkdir -p /pics/CrossBuild/embedded/rpi2/_.w/packages
+ cp
/pics/CrossBuild/src/tools/tools/nanobsd/packages/dhcpd-5.8.20151202.txz
/pics/CrossBuild/src/tools/tools/nanobsd/packages/net-snmp-5.7.3_11.txz
/pics/CrossBuild/src/tools/tools/nanobsd/packages/ntimed-0.0.2015.01.30.txz
/pics/CrossBuild/embedded/rpi2/_.w/packages
+ chroot /pics/CrossBuild/embedded/rpi2/_.w sh -c 'cd packages; pkg_add
-v *;cd ..;'
chroot: sh: Exec format error

You chroot into there and the image you're attempting to "pkg_add" with
it an arm executable, which of course my nice Amd64 processor cannot
grok..... Fixing that might get kinda messy (are the databases even
compatible across architectures?)
