Great! I was just looking for this! Unfortunately there seems to be
something missing: by the time we run the first yum command, there's no
distroverpkg package installed under $LIVE to query for $releasever.
My output is:
--------------
# yum -c $LIVE/etc/yum.conf --installroot=$LIVE install yum
Setting up Install Process
Setting up repositories
not using ftp, http[s], or file for repos, skipping - Null is not a valid
release or hasnt been released yet
Cannot find a valid baseurl for repo: update
Error: Cannot find a valid baseurl for repo: update
---------------
Should the user install centos-release RPM with prefix equal to $LIVE
beforehand?
Or is there any other easy but correct way to pass this variable to yum?
