Launched in 2004, dmesgd aims to provide a user-submitted repository of searchable *BSD dmesgs. The dmesg(8) command displays the system message buffer's content, and during boot a copy is saved to /var/run/dmesg.boot. This buffer contains the operating system release, name and version, a list of devices identified, plus a whole host of other useful information. We hope others find this resource useful and further contribute to its growth. Contact us at [ admin at lists dot nycbug dot org ].
