有什么办法可以告诉 yum 变量解析器变量名的开始和结束位置吗？

我在嵌入时遇到问题$releasever。

例如，这有效：

# cat test.repo
[RHEL$releasever]
name=RHEL$releasever test
# yum  repolist
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
repo id                   repo name         status                                                                                      
RHEL6                     RHEL6 test        0                                                                                           
repolist: 0
#

但这不是：

# cat test.repo
[RHEL$releasever_SOMETHING]
name=RHEL$releasever test
# yum repolist
Loaded plugins: fastestmirror, refresh-packagekit, security
Bad id for repo: RHEL$releasever_SOMETHING, byte = $ 4
Loading mirror speeds from cached hostfile
repolist: 0
#

唉，yum 不识别${releasever}或$(releasever) -- shell 风格和 …
