RE: use install paramter in postinstall script

["Shabazian, Chip" <chip.shabazian@xxxxxxxxxxxxxxxxx>]

Keep in mind that you have a total character limit of 255 characters on the command line.  As long as you can keep it short enough, parsing the command line is a nice easy way to pass parameters to the build, whether it’s in the %pre or the %post.

I do something like this:

%pre
cat /proc/cmdline > /tmp/cmdline

%post --nochroot
cp /tmp/cmdline /mnt/sysimage/tmp/cmdline

%post
# Process using /tmp/cmdline from inside chroot environment

Repeat for other variables you want to carry forward.

kickstart doesn't have any variables so you'll either have to write
these values out to another file in your %post, or duplicate the above
code in your %post.
