Hi there all.

I bought two microSD cards with adapters of course to have some mooore GB on my n800. So, one of them (Those cards) is really, I mean REALLY fast, In my test up to 24mb/s of write with avg. 18,8, and almost 35mb/s of read with avg 31.

Card doesn't cause any problems. Now Im using only maemo 4 - Diablo booted from flash memory, so Im in need for swap, new fast card can deliver but Im tired of sending echo after I reboot the device.

Is there any way to set the swappiness value permanent? Like editing rcS file on n900?

You can add create a new file in /etc/init.d/, lets say you call it "foo". Run this command to add the file to runlevels 2, 3, 4 and 5. Any commands you put in the file will run everytime the system starts.

Code:
update-rc.d foo start 99 2 3 4 5 .

Done that but doesn't work.

when I try to update again it's says that links to "foo" file exist already.

foo file containts alone and only

echo 75 > /proc/sys/vm/swappines

which works alone from console, but after reboot swappiness is still default, 1.

Sorry, forgot to mention you need to add #!/bin/sh on the first line of the file and set its permissions to 755.

foo contents:
Code:
#!/bin/sh

echo 75 > /proc/sys/vm/swappines
type on command line:
Code:
chmod 755 /etc/init.d/foo
You might also want to name it something like my-startup-commands instead of foo.

If you do, remove foo from runlevels with this command:
Code:
update-rc.d -f foo remove
And then run the other update command for new file name.

Edit:
Only run update once to install the script, you don't need to run it for any changes to the script.
