Test5 answer: "dphys-swapfile setup" run only one time (I also tested
if /etc/init.d/dphys-swapfile still run, the answer is no)

I have not got "dphys-swapfile setup" exit code. It seems that it give
a question mark.
"dphys-swapfile setup" exit with false code altought "dphys-swapfile
setup" seems to went okay for me, because I can run
"/sbin/dphys-swapfile swapon" successfully.
I will see if I can get the exit code from the 64-bit environment tomorrow.
