After installing QRTP and the first boot action … I found the
…swapfile in
/pkgs/base/qnx/o … size 32 bytes 
)
I have deleted it and re-created it with swapctl successfully … so it
seems that I’m not
the only one who is confused by this doubled root dirs
df /
/pkgs/base/qnx/o 0 0 0 100% /
df /dev/hd0t79
/dev/hd0t79 20081187 846187 19235000 5% /
