This bug has been reported 4 times on different versions and has been closed as fixed in every case, and yet the rpm package STILL overwrites the /etc/sysconfig/mongod file, replacing it with an empty file.
The problem is present in all versions of the mongodb rpms that i have installed from tne 10gen repos. Versiins 2.4, 2.6 and 3.0. It is a major hazzard to production systems that may rely on tbe ability to override configuratiin in the sysconfig file.
To be clear, if an existing /etc/sysconfig/mongod file exists it should never be over written by the rpm installer, if there are important new options in tne file then it should be created with a .rpmnew extension.
This defect is a major pain in the ass when upgrading servers.
