You can experiment with moving /usr/obj//home/guru/9-CURRENT/src to
/usr/obj/usr/src

you can see /usr/share/mk/bsd.obj.mk for details. make(1) creates
directory ${MAKEOBJDIRPREFIX}/${.CURDIR} . It is useful when you make
world for yourself, do some development stuff with another things,
etc.

I do installation with another method:
On build server I make world, install it into some directory, and make
cpio(1) archive to save file rights. Then I copy archive to usb and
unpack it into new system.

One more question for community: does cpio(1) archive format save file
flags (see chflags(1))?
