Building FreeBSD to install or update in two DESTDIRs

REALLY can't help you without any info attached.

As from your description it just have to work and you did all fine.

anyway i usually just do installs to DESTDIR=/something, then tar.gz it 
up, and untar whenever i need (but separately tar.gz for /boot/kernel 
subdir)

use --unlink option when untarring on live system.
