Question:
Upon running the Centrify rpmlint command against Centrify DirectControl package, it may show the following warning message.

CentrifyDC.x86_64: W: dangerous-command-in-%pre chmod

What is the significance and impact of this warning message on Centrify DirectControl?

Answer:

Centrify has researched this command and determined that the command is flagging our use of chmod in our package script. This is being done to safeguard the Centrify installation directory and in our conclusion is a safe action given the circumstances. As reported by the output, it is a warning message only intended to notify and not reported as an error level message.

For reference here is what will happen when you run the rpm command with a specific Centrify package.

$ rpm -qp --scripts CentrifyDC-5.4.1-rhel4.x86_64.rpm | grep chmod

Observing the following output broken down into three different parts with clarification.

First part, this is to ensure integrity of the run time settings directory
chmod 755 /var/centrifydc >> ${LOG_FILE} 2>> ${LOG_FILE}

Second part, these are to ensure the integrity of the machine GP settings directory (${REG_DIR} = /var/Centrifydc/reg)
find ${REG_DIR}/machine/secedit/ -type d -exec chmod 700 '{}' \;
find ${REG_DIR}/machine/secedit/ -type f -exec chmod 600 '{}' \;
find ${REG_DIR}/machine/software/ -type d -exec chmod 700 '{}' \;
find ${REG_DIR}/machine/software/ -type f -exec chmod 600 '{}' \;
chmod 600 ${REG_DIR}/machine/applied_policies
chmod 744 ${REG_DIR}/machine/gp.report

Third part, these are to ensure the integrity of the user GP settings directory (${REG_DIR}/users/)

find $user/* -type d -exec chmod 700 '{}' \;
find $user/ -type f -exec chmod 600 '{}' \;
chmod 755 /var/centrifydc >> ${LOG_FILE}
