It does so by monitoring the usage of several system components periodically. Based on that information components will then be put into lower or higher power saving modes to adapt to the current usage. Currently only ethernet network and ATA harddisk devices are implemented. .SH OPTIONS .TP 12 .BI \-d "\fR, \fP" \--daemon This options starts tuned as a daemon as opposed to in the foreground without forking at startup. .TP 12 .BI \-c "\fR, \fP" \--conffile=" conffile" Specify the name and path of the configuration file, default is \fB/etc/tuned.conf\fR. .SH BUGS If you are using tuned together with NetworkManager at the moment NetworkManager will completely stop and start a managed device when tuned switches power saving levels. This happens because the network device will loose it's physical link for a very short time when it performs a power saving switch and NetworkManager can not distinguish this from a connectivity loss. This will be resolved in future versions of tuned and NM where NM will gain the mechanism to switch speeds for network devices. .SH "FILES" .nf /etc/tuned.conf .SH "SEE ALSO" .LP tuned.conf(5) .SH AUTHOR Written by Phil Knirsch . .SH REPORTING BUGS Report bugs to .
