Description Gene Czarcinski 2005-02-21 10:51:35 EST
Description of problem:

DVD drives and use of DVDs to hold distributions are becoming more and
more common.  Unfortunately, the current splittree.py script does not
support splitting the distribution tree into two DVD images.  At one
time (Fedora Core 1) the total distribution could fit on one DVD. 
With Fedora Core 3 (and expect FC4) this is no longer true ... the
total of binary plus source packages exceeds the capacity of a DVD
although there is plenty of space if source and binary are put onto
separate DVD iamges.

While this splitting can be accomplished manually, it is more
consistent (and less error prone) for splitttree.py to support
splitting into DVD images.  This could be accomplished with a separate
splittree.-dvd.py script or actually modifying splittree.py to accept
an additional keyword parameter to specify CD or DVD.

The actual changes necessary are in two messages on anaconda-devel-list:

About line 79 you'll find this:
self.target_size = 640.0 * 1024.0 * 1024

Change that to:
self.target_size = 4.4 * 1024.0 * 1024.0 * 1024

I also substitute "-dvd" everywhere "-disc" appears so that CD
directories and dvd directories can coexist.

I have not programed much in python or I would submit a patch here. 
However, if you would be receptive to a patch, I will see what I can
do something which would support CD and DVD splitting with a single

Fedora Core 3 is now maintained by the Fedora Legacy project for security
updates only. If this problem is a security issue, please reopen and
reassign to the Fedora Legacy product. If it is not a security issue and
hasn't been resolved in the current FC5 updates or in the FC6 test
release, reopen and change the version to match.

Thank you!

Added a --disc-size option to splittree.py that allows you to set the size of
the media to be used, in megabytes.  This will be in the next build of anaconda.
