Your symlink trick is clever but I don't recall any serious measurement of
performance.
it's not because of performance, it's because this how i picked packages
to downgrade:
0. cd /var/spool/repackage
1. ln -s */python*.rpm .
2. ln -s */somethingelse* .
3. rm *not*this*.rpm *not*that*.rpm
4. ls # to verify
or you mean my own performance? yes, i performed the upgrade a lot
faster than looking each package which needed downgrade as well due new
python bytecode dependency missing :)
i personally don't like --force & --nodeps (like gotar snippet),
so i tried to pick packages that resulted all dependencies remaining
okay after downgrade.
