There is no rollback, we are planning on some form of functional
"downgrade" in the near future. However the bigger than gets the less
likely it will be to be happy (for CentOS-5.3 => CentOS-5.2 is
very likely to not do what you want).

There is a /var/log/yum.log ... but it doesn't say the above on one
line, but then rpms don't work quite the same way debs do.

yum-debug-restore | yum shell (note not in yum-utils, yet, buyer
