Several kickstart -% post priority

[JakeR]

I have a kickstart which includes several other ks files. One of them is /usr/share/spin-kickstart/fedora-live-desktop.ks.

The fedora-live-desktop.ks %post creates some files that I need to modify.

How to determine the order of %post in all the included ks files? I can not get my %post script to run after fedora-live-desktop.ks.

Hi JakeR,

That is a good question, Normally the %post sections from the %include are run first. But when a .ks that is called by %include calls another .ks with %include the second included %post runs first.

So if you want a %post section to be run last it is usually safe to add that %post section to the .ks you are calling with livecd-creator.

You can add a line to all the .ks's at the beginning of the %post sections that will show you during the build when they are ran by adding a line like this for live-base:

%post
echo "**************This is the beginning of the post section of live-base*********************"

or for fedora-live-desktop:

%post
echo "***************This is the beginning of the post section of fedora-live-desktop***************"

Hope this helps,

Hi

Thank you. I want to override (rm files) in the corresponding .ks file. In my example, I want to run foobar-live-desktop.ks %post after fedora-live-desktop.ks %post.

# foobar-livecd-desktop.ks
%include foobar-live-base.ks
%include /usr/share/spin-kickstarts/fedora-livecd-desktop.ks
%include foobar-live-desktop.ks
[...]

# foobar-live-desktop.ks
%include foobar-live-base.ks
%include /usr/share/spin-kickstarts/fedora-live-desktop.ks
[...]

This "include structure" is logical (one foobar*.ks per fedora*.ks), but fedora-live-desktop.ks will be included twice (directly by foobar-live-desktop.ks and indirectly by foobar-livecd-desktop.ks). Is it a problem?

I can't call foobar-livecd-desktop.ks and get the %post in foobar-live-desktop.ks to run after %post in fedora-live-desktop.ks?

Hi JakeR,

You could add a second %post to the end of all the fedora*.ks with the corresponding foobar*.ks %post contents in the second %post and not run any separate foobar*.ks. That would eliminate the issue you are seeing with regards to the called order.

If for some reason this is not a acceptable method I would suggest you present this question to the livecd mailing list as that would be the most likely place to get a different working answer. : https://lists.fedoraproject.org/mailman/listinfo/livecd

Hope this helps,
