[edit] Feature Wrangler Review (2008-12-09)

Please update the following items and change the category of this page to Category:FeatureReadyForWrangler once they are completed. The feature wrangler's have a watch on this page and will see your changes.

1. Please complete documentation section. It could be as simple as a few good URLs to upstream's documentation
2. Please complete release notes section with the proposed text which would announce and draw attention to this new feature

[edit] Is upstart ready?

Is upstart ready to handle parallel startup and become a true event-driven system? I recall some discussion on that during F10, might want to get Casey Dahlin to weigh in on that.

Harald: upstart-0.5 would be ready for the basic use case of moving essential services from SysVInit style to upstart and start them in parallel.

[edit] QA review - 2009-01-01

The Scope section of this feature is somewhat lacking. One of the items that we're looking for is "what would constitute success or failure of this feature", rather than simply a list of packages that must be modified in order to implement. --Jstanley 03:22, 2 January 2009 (UTC)

Harald, have you seen the correponding OpenSUSE efforts ? http://en.opensuse.org/Boottime/Boot_time

There's also the Mandriva effort: http://lists.mandriva.com/cooker/2009-02/msg00131.php

[edit] readahead + SSD ?

There have been reports that when using SSD drives, readahead only makes the performance worse (because there's 0 seek time with SSD drives). There should probably be an option to disable readahead easily -- or even automatically. Ksvist 23:52, 24 March 2009 (UTC)

Harald: Edit /etc/sysconfig/readahead or "rpm -e readahead". Yes, you are right, it would make sense to provide a tool, to easily switch it off.
