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
‘/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.
