Assuming both your pre & post scripts are ran in a "nochroot" environment, then you can use a temporary file location under /tmp. I'll use a few of your variables as examples and let you fill in the rest:
%pre script excerpt: cat <<EOF > /tmp/custom_vars hostname=$hostname2 # spelling correct? ip=$ip token=$token rack=$rack EOF That is called a "here-document" and you can find more details about it in your local bash(1) manpage. Later in your %post script, you can source it via the "." operator or keyword "source": source /tmp/custom_vars echo "Relearned that my IP is $ip" -- Jon Miller On Thu, Jun 6, 2013 at 12:51 PM, Corey Hemminger < [email protected]> wrote: > How do I re-source them in the %post script?
