安裝過時的包而不刪除過時的包

有沒有辦法在使用 yum 過時的軟體包旁邊安裝過時的軟體包？有幾個衝突的文件，但這些包可以與這些文件的最新版本共存。

過時軟體包的正常安裝會刪除過時的軟體包：

# rpm -qa | grep tc-server
vfabric-tc-server-standard-2.9.7-RELEASE.noarch

# yum -y install pivotal-tc-server-standard vfabric-tc-server-standard
---> Package pivotal-tc-server-standard.noarch 0:3.2.1-RELEASE will be obsoleting
---> Package vfabric-tc-server-standard.noarch 0:2.9.7-RELEASE will be obsoleted
...

Installed:
 pivotal-tc-server-standard.noarch 0:3.2.1-RELEASE

Replaced:
 vfabric-tc-server-standard.noarch 0:2.9.7-RELEASE

# rpm -qa | grep tc-server
pivotal-tc-server-standard-3.2.1-RELEASE.noarch

我試過：

yum -y --setopt=obsoletes=0 install pivotal-tc-server-standard vfabric-tc-server-standard

yum -y install pivotal-tc-server-standard --exclude=vfabric-tc-server-standard

這似乎與正常安裝沒有什麼不同。

我也試過：

# yum install pivotal-tc-server-standard --setopt=protected_packages=vfabric-tc-server-standard
---> Package pivotal-tc-server-standard.noarch 0:3.2.1-RELEASE will be obsoleting
---> Package vfabric-tc-server-standard.noarch 0:2.9.7-RELEASE will be obsoleted
Error: Trying to remove "vfabric-tc-server-standard", which is protected

我還沒有弄清楚如何使用 yum 來做到這一點。以下是有效的方法：

# yum -y install yum-utils
# yumdownloader pivotal-tc-server-standard
# rpm -i --replacefiles pivotal-tc-server-standard-X.X.X-RELEASE.noarch.rpm

# rpm -qa | grep tc-server
vfabric-tc-server-standard-2.9.7-RELEASE.noarch
pivotal-tc-server-standard-3.2.1-RELEASE.noarch
