An updated upstart package that fixes two bug and adds two enhancements is now available for Red Hat Enterprise Linux 6.
The upstart package contains an event-based replacement for the /sbin/init daemon that starts tasks and services during boot, stops them during shut down, and supervises them while the system is running.
Previously, the PACKAGE_BUGREPORT variable pointed to a Ubuntu mailing list. The mailing list was therefore presented in multiple manual pages, which was unwanted. With this update, the value of the PACKAGE_BUGREPORT variable has been modified to "https://launchpad.net/upstart/+bugs", and users are now directed to that website rather than to the Ubuntu mailing list.
Previous versions of upstart did not mount the proc and sys file systems. This was ensured by initscripts, which could, under certain circumstances, lead to race condition problems. With this update, upstart is used to mount the proc and sys file systems before launching anything else.
Files with the ".conf" suffix located in the /etc/init/ directory are not considered as configuration files. As a consequence, such files are not protected during a package update and can be overwritten by new files. This update adds support for "override" files that contain user-specified settings. Now, it is possible to alter parameters provided by the aforementioned ".conf" files by creating a corresponding file with the ".override" suffix.
Previously, the initctl scripts returned error messages that did not tell users how to run the particular command correctly to get the required output. This update adds a new stanza, "usage", that can be used to provide users with detailed information on how to run the particular command correctly if the input has been incorrect.
All users of upstart are advised to upgrade to this updated package, which fixes these bugs and adds these enhancements.
