Red Hat Bugzilla – Bug 88007
kickstart 8.0 ignores I/O redirectors in POST section
Last modified: 2007-04-18 12:52:46 EDT
Description of problem: IN 7.2 and 7.3 this post script worked fine. In Version 8.0 it completly ignores the commands. I have tried enclosing the whole string in back tics and that does not work. I have tried specifying /bin/sh as the interpreter and that does not work, I have tried specifying nothing to the interpreter (like with 7.2 and 7.3) and that does not work either. # This is the syntax which should work as it did in previous versions! %post /bin/cat <<MOTD >/etc/motd Red Hat Linux 8.0 Kickstart-installed COMPANY NAME UNAUTHORIZED PERSONS WILL BE PROSECUTED TO THE FULL EXTENT OF THE LAW All Trafic is Logged and Monitored on remote machines MOTD # This is the only way it will work now which is ridiculous! %post --interpreter /bin/sh echo "========> Setting MOTD" `/bin/echo "" >/etc/motd` `/bin/echo " Red Hat Linux 8.0 Kickstart-installed `/bin/date`">>/etc/motd` `/bin/echo "">>/etc/motd` `/bin/echo " ???

(use above with own encrypted password added) Steps to Reproduce: 1. Use kickstart above but enter in you own encrypted password 2. Run any commands in the post section with /bin/sh 3. That's it. Actual results: The install works fine accept all the custom configuration done foe each individual machine is lost as the I/O directors "<<EOF" are ignored and actually error out if you what the F4 console at the end of the install. Expected results: The I/O operators should be followed and the hosts file, ntp file and motd file should all be changes with the text that is pushed to them. There is no error output when I use the /bin/sh as interpreter but the commands do not get executed.
This sort of thing certainly works for kickstart in Red Hat Linux 9, FWIW. Redirection is a shell thing, not sh-utils. Besides, since shell redirection certainly works in 8.0, this must be something wrong in anaconda.
This works fine for me. Do you mistakenly have DOS line returns at the end of your lines or something similar?
The script is generated the same way as it was for 7.2 and 7.3. Perl writes out the file from a script. I have opended the file in vi and there are no visable ^M. I also ran the script through dos2unix and again the post instructions failed to work. The F3 console displays "command not founde 1:"
Ok chaps, sorry! you are right. There was an extra whitespaces at the end of 5 lines which was casuing the "post" to tank. Not sure why it worked on the 7.2 and 7.3 but I apologize for the wild-goose-chase! I tried everything else and even dos2unix was not help, which of course it wouldn't be in this situation. Thanks!
Great, glad you tracked it down.
