do_install taskes run under our fakeroot emulator, pseudo. Our builds
don't have root privileges so it stores our emulated owners/modes in a
sqlite database (see ${WORKDIR}/pseudo). This is why as a normal user
you'd see something different to what the task sees when the fakeroot
emulation is running. "bitbake bluez -c devshell" will drop you into
that fakeroot context assuming you have a terminal setup that works
with devshell.
