The only DRM in diskboot is that if it doesn’t find a license it will
print out the message.
There were claims in that thread that the DRM had nothing to
do with the problem, but nothing definitive. There was this,
from Keith Russell at QNX:
First, my apologies for not getting to this sooner. I only
became aware today…
At first glance I would agree with Colin that the license
issue is not related (it would be related to the mounting
diskboot does when running in safe mode). It would appear
that diskboot is broken w.r.t. to the debug shell and/or
safe mode.
I have run in safe mode to get to a standard login many times,
typically when I mess up my Photon settings. I have yet to
see this problem. Though it looks easy to reproduce.
I’m looking into it and will post my findings shortly.
But there was never a definitive answer in the qnx.rtos
newsgroup. It took a month to get to the point that
the problem was clearly acknowledged. And diskboot
worked before someone messed with it to put in DRM.
Further along in the current thread, there’s this, from
Dave Young at QNX:
The advice I gave to Mike to pass along to you is incorrect (my error).
On closer inspection it sounds like it it the licensing of the Sandpoint BSP
that is busted after the uninstall.
I’m trying to reproduce the issue now. I will post more when I can isolate
the cause (hopefully today).
So there’s yet more DRM. And it wasn’t admitted until it gave a
user trouble. One bug at a time, users have to discover and
disarm the self-destruct devices.
Also note this thread over on
http://www.openqnx.com/PNphpBB2-viewtopic-t4319-.html
where someone is beating their head against the wall trying to get
the Sandpoint BSP to boot on a target machine. Could that be
DRM-related? They spent months on that problem, and seem to have
finally given up.
These are only some of the ways DRM increases business risk
for customers and substantally increases the total cost of
ownership of QNX.
With free versions of embedded Linux available for
most of the platforms QNX targets (see “http://www.timesys.com”)
QNX is shooting itself in the foot here. Piracy of QNX is
not a problem. Declining market share is.
