Description Marcelo Moreira de Mello 2011-03-11 00:45:04 EST
Description of problem:

When kickstart is rendered, an runtime execution error is found when running insmod /lib/ext4.o. Kickstart script is missing the syntax 'then'

Kickstart is rendered as below: 

echo "Saving RHN keys..." > /dev/ttyS0

insmod /lib/jbd.o
insmod /lib/ext3.o

if [ -f /lib/ext4.o ];
    insmod /lib/ext4.o

Version-Release number of selected component (if applicable):
Red Hat Satellite 5.4

How reproducible:

Steps to Reproduce:
1. Create a kickstart
Actual results:

Kickstart is rendered with a error in syntax for Bash script: 

insmod /lib/jbd.o
insmod /lib/ext3.o

if [ -f /lib/ext4.o ];
    insmod /lib/ext4.o

Expected results:

Kickstart executes with no errors: 

if [ -f /lib/ext4.o ]; then
    insmod /lib/ext4.o

# if [ -f /lib/ext4.o ];then    insmod /lib/ext4.o; fi

Additional info:

=== Not Working

[root@server]# if [ -f /lib/ext4.o ];     insmod /lib/ext4.o; fi
bash: syntax error near unexpected token `fi'
[root@server]# echo $?

=== Working
[root@server]# if [ -f /lib/ext4.o ];then    insmod /lib/ext4.o; fi
[root@server]# echo $?
Comment 1 Marcelo Moreira de Mello 2011-03-11 00:57:13 EST

Investigating the issue, we found the RCA: 

[root@sat-server]# ls -la /var/lib/rhn/kickstarts/snippets/keep_system_id 
-rw-r--r-- 1 tomcat tomcat 1799 Feb 17 09:05 /var/lib/rhn/kickstarts/snippets/keep_system_id

[root@sat-server]# rpm -qf /var/lib/rhn/kickstarts/snippets/keep_system_id

[root@sat-server]# grep ext4 -B 2 -A 2  /var/lib/rhn/kickstarts/snippets/keep_system_id

insmod /lib/ext3.o

if [ -f /lib/ext4.o ];
    insmod /lib/ext4.o

[root@sat-server]# rhn-schema-version
