How to modify default value for swappiness?

[Giovenale]

It's very easy in Debian, adding a string to /etc/sysctl.conf

vm.swappiness=<new value>

I've tried this solution also on Boss 64-bit setting "15" for swappiness, but it doesn't run: after a reboot, the value goes back to the system default (60).
Using the string

echo 15 > /proc/sys/vm/swappiness

to change it "on the fly", all runs correctly.

this was covered in this post for Boss I don't think anything has changed,

also this link explains more about it and the effects http://kerneltrap.org/node/3000

Thanks, mandog. I've solved copying the instruction

echo 15 > /proc/sys/vm/swappiness

in a script and launching it with sudo, together the other applications in Xfce Session's Autostart.

P.S. Talking about kernel: congratulations for the 2.6.26-parsix64-18 #1 SMP recently released, the speed of the system has very increased.
