Hello, This is now resolved via the YUM mailing list.
There is a deficeincy in the yum documentation. The yum man pages fail to detail the required files and directory structures that are required to. PRE-EXIST in the —installroot path. 'yum —installroot' could not substitute the proper $slreleasever value into the output URL because the expected directories and files, located ‘<INSTALL_ROOT>/etc/yum/vars/….’, did not exist. By placing the proper config etc/... files and directories into the INSTALL_ROOT path yum was able to generate the base file system. With any luck the man pages will be updated to include this important information.
