install_mu Does Not Function Correctly if Started With sh (4062334)

Because of problems that stem from the interactions between sh(1) and ksh(1), the install_mu utility might fail to install certain patches correctly. This failure occurs when you start the utility by using the following command from the command line or from an administrative script:

# /bin/sh ./install_mu options

Workaround: Execute install_mu from the command line or from an administrative script as follows:

# ./install_mu options
