Limitations of RPMLimitations of RPM

• Each product should be installed only once per machine

• Parallel test and production systems

• Different products installed in the same directory can only have each file name once

• CSDK on top of database server

• To use graphical tools, user interaction and environment variables should be avoided

• $INFORMIXDIR• Licensing
