[CentOS] more kickstart - saving %pre decisions for %post
Hey again folks,
How can I save answers to questions in %pre, for use in %post?
I'm assuming (though have not yet tried) that variables won't live that
long.
Could I save them off to /tmp in a file, and retrieve them?
e.g.
%pre
echo "VARNAME=$VARNAME" >> /tmp/varfile
%post
grep ^VARNAME= /tmp/varile
Or some such ...

Why not store it in memory registers or I have your idea wrong? John

So be sure to put it in the correct tmp... http://www.redhat.com/docs/manuals/enterprise/RHEL-5-manual/Installation_Guide-en-US/s1-kickstart2-postinstallconfig.html JD
