Description Will Woods 2008-01-24 11:44:57 EST
Anaconda attempts to check the arch of the target system to make sure it matches
the arch of the installer. It does this by checking the contents of
/etc/rpm/platform.

Unfortunately, if that file doesn't exist, there's no fallback, and the
installer traces back.

There should probably be a fallback method - perhaps reading some info from the
rpmdb would help?

Traceback is attached.

Comment 2 Jeremy Katz 2008-01-29 11:47:41 EST
We can't require that this file be present -- some people remove it, it's not
there for live installs, etc.

Have a fallback for determining architecture

We have something like this in yuminstall.py, but i think this is more general
and it would be possible to use it in _checkUpgradeArch in there as well.

But I'm not sure about the rpm database stuff (what about database locks?) and
also the python-magic module will be new in the stage2 image (cca 300KB).

Without those two concerns, the code works on at least 4 machines here in the
office.
Comment 4 Seth Vidal 2008-02-22 10:31:39 EST
If we're lacking an /etc/rpm/platform where's the harm in relying on os.uname()?
Comment 5 Martin Sivák 2008-02-22 10:38:09 EST
Uname will tell you the architecture of running kernel. But to notify user about
the difference between running kernel (instalation media architecture) and the
architecture he already has installed, you need to read something from the
installed system (which is not running at the moment).

I'm waiting for installable rawhide to test the upgrade with modified patch
Comment 7 Jeremy Katz 2008-03-05 13:52:50 EST
Rawhide should be pretty installable at this point

anacdump.txt

Still happens with current rawhide. New anacdump.txt attached.
