'''Answer the Investigation 6 observations / questions in your lab log book.'''
== Investigation 7: Kickstart Files ==
Even when you perform a non-Kickstart installation, the installation program creates a Kickstart file in the <code>/root</code> directory for reference.
# Obtain the kickstart files for all four of your installations (your disk pack ''c6hostc7host'', plus the ''centos1'', ''centos2'', and ''centos3'' virtual machines).
# To prevent confusion, copy your kickstart files to kickstart filenames that describe their purpose (eg. kickstart_host, kickstart_centos1, kickstart_centos2, etc...)
# Copy them all to your c6host c7host system (tip: use <code>scp</code>, webmail, or command-line mail. Refer to the manpages for help).
# Compare these files. What are the differences? Similarities? (Tip: you may want to use tools such as <code>sdiff</code> to help with the comparison).
# How could you use the kickstart file produced by the installation program to perform additional, identical installations?
