performance-enhancing behavior is less than helpful. When your Gentoo Linux |
| 2270 |
system is up and running, you can send metalog a USR1 signal to temporarily |
| 2271 |
turn off this message buffering (meaning that <c>tail -f |
| 2272 |
<path>/var/log/everything/current</path></c> will now work in real time, as |
| 2273 |
expected) and a USR2 signal to turn buffering back on again. If you want to |
| 2274 |
disable buffering permanently, you can change METALOG_OPTS="-B" to |
| 2275 |
METALOG_OPTS="-B -s" in <path>/etc/conf.d/metalog</path>. |
