yum update from F10 to rawhide

[M A Young]

A lot of people seem to have been having trouble with using yum to update 
from F10 to rawhide, so I thought I would try it. My tests were as follows
1. yum update (still in F10, checking afterwards that I have at least
rpm-4.6.0-1.fc10.x86_64)
2. yum update --enablerepo=rawhide
This fails, due to a couple of packages that don't have F11 versions, the 
errors ending with
audit-libs-python-1.7.12-3.fc10.x86_64 from installed has depsolving 
problems
   --> Missing Dependency: python(abi) = 2.5 is needed by package 
audit-libs-python-1.7.12-3.fc10.x86_64 (installed)
python-psycopg2-2.0.9-1.fc10.x86_64 from installed has depsolving problems
   --> Missing Dependency: libpython2.5.so.1.0()(64bit) is needed by 
package python-psycopg2-2.0.9-1.fc10.x86_64 (installed)

   --> Missing Dependency: python(abi) = 2.5 is needed by package 
python-psycopg2-2.0.9-1.fc10.x86_64 (installed)
Error: Missing Dependency: libpython2.5.so.1.0()(64bit) is needed by 
package python-psycopg2-2.0.9-1.fc10.x86_64 (installed)
Error: Missing Dependency: python(abi) = 2.5 is needed by package

audit-libs-python-1.7.12-3.fc10.x86_64 (installed)

The problem for both of these packages (python-psycopg2 and 
audit-libs-python) is that F10 version > rawhide version
3. rpm -e python-psycopg2 audit-libs-python
error: Failed dependencies:
         python-psycopg2 is needed by (installed)

4. rpm -e python-psycopg2 audit-libs-python --nodeps
(Having checked by the previous command that we aren't going to break 
anything too important - rpm works because we haven't installed anything 
from rawhide yet)
5. yum update --enablerepo=rawhide --disablerepo=updates
(if we don't turn off updates the F10 versions of python-psycopg2 and 
audit-libs-python will try to come back and confuse things)

This ends with the error
Transaction Check Error:
   package audit-libs-1.7.12-3.fc10.x86_64 (which is newer than 
audit-libs-1.7.12-2.fc11.i586) is already installed
   file /etc/libaudit.conf from install of audit-libs-1.7.12-2.fc11.i586 
conflicts with file from package audit-libs-1.7.12-3.fc10.x86_64

6. rpm -e audit audit-libs --nodeps
(A bit risky, because this might break a few things, but nothing directly
related to the upgrade)

7. yum update --enablerepo=rawhide --disablerepo=updates

This works.

So it is possible to upgrade from F10 to rawhide if you are careful, and 
any problems are because rawhide is lagging a bit behind F10 updates, 
presumably because of the beta freeze.
