Ошибка обновления vzctl на RHEL/CentOS 5.x - решение

После выхода vzctl-4.0 появилась проблема с обновлением vzctl на RHEL/CentOS 5.x. Ошибка выглядит примерно так

# yum upgrade vzctl

 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest

Вчера в блоге OpenVZ нашлось решение этой проблемы. Если кратко то решение выглядит так:

# yum shell
> remove ploop ploop-lib
> update vzctl
> run

Поскольку поддержка ploop есть только в ядрах для RHEL/CentOS 6.x, то ploop можно смело удалить в RHEL/CentOS 5.x.
