Re: Kickstart-list Digest, Vol 132, Issue 3

[Spike White <spikewhitetx@xxxxxxxxx>]

<CR><LF> terminators in a ks.cfg file are a strange beast.

Apparently the anaconda parser can tolerate them.  So it works in a %packages section, or other anaconda-parsed sections.  Like the top, overall section.

However, anaconda passes off %pre sections and %post sections to the bash interpreter.  Which doesn't tolerate <CR><LF> terminators.  So you can't have <CR><LF> in a %pre or %post section.

%include literally embeds the content of the specified file in place.  So by extension, the same rules apply.  <CR><LF> in that file would be tolerated in certain sections, not in the %pre or %post section.

My bad. Need to adjust my glasses. The parser caught me on the file extension; .ks versus .sh. All is well now.

 

But for the first point, I have never seen anyone comment on carriage returns showing up at the end of command execution if the %pre script is embedded in the Kickstart file. The clue for the work around was in an Oracle doc showing the script %included in the kickstart file.

Subject: Not finding /tmp/include created in %pre

 

First, I had to work around the fact that the execution of shell commands are terminated with a carriage return including file names that are created during %pre. The work around was simply:

%pre

%include http://<ip>/path/to/script.sh

%post

 

In this script.sh I write out network commands for 4 interfaces after capturing input from tty6.

I write to /tmp/net-include and, using alt-F2 shell terminal, I can readily see it in /tmp

 

The %include /tmp/net-config in the kickstart file is generating a PYCURL ERROR 22 … 404 not found once parsed after the %pre section %end’s.

 

Why are these simple looking things that have many similar examples on the web not working?
