sorry for creating another Rootfs free space thread, but thought this would be helpfull for a lot of people and easier to find if at the start of a new thread!

It's true, 95.1MB free in Rootfs;
Filesystem Size Used Available Use% Mounted on
rootfs 227.5M 128.3M 95.1M 57% /

However, I have now installed loads of apps, including many from Development and am now down to 92.8MB!

~ $ df -h
Filesystem Size Used Available Use% Mounted on
rootfs 227.5M 130.6M 92.8M 58% /

So how did I get there?
First I was robbed, had my 3 month old N900 stolen! Had to buy a new one urgently, so had a brand new N900 to start with.

Being aware of the Rootfs problems I decided to optimise it before installing any apps.

The brand new N900 had 83.3MB free
~ $ df -h
Filesystem Size Used Available Use% Mounted on
rootfs 227.5M 140.0M 83.3M 63% /


After updating to firmware 51 I was down to 72MB with no apps installed.
~ $ df -h
Filesystem Size Used Available Use% Mounted on
rootfs 227.5M 151.2M 72.1M 68% /


Next I moved var/cache/apt but forgot to copy the df -h results!

Then I decided to use a script to move some foldes and symlink them. The script i used was created by Tom Tanner (thanks Tom)
and is available with instructions here;
http://wiki.maemo.org/User:Tanner#Safely_free_some_space_on_rootfs


Running the script gave me these results;

/home/user/MyDocs # sh Optify.sh
Optify.sh: line 1: #!/bin/sh: not found
5952 usr/share/icons
8932 usr/share/nokia-maps
14720 usr/share/themes
3968 usr/share/fonts
10548 usr/share/locale
16960 usr/lib/locale
3232 var/lib/apt
0 var/cache/apt
64312 total
moving /usr/share/icons
moving /usr/share/nokia-maps
moving /usr/share/themes
moving /usr/share/fonts
moving /usr/share/locale
moving /usr/lib/locale
moving /var/lib/apt


At this point I had achieved my maximum free Rootfs of 95.1MB;

/home/user/MyDocs # df -h
Filesystem Size Used Available Use% Mounted on
rootfs 227.5M 128.3M 95.1M 57% /

Since this I have installed all my preferred apps, including a lot of "Risky Development Apps" and I still have 82.5MB free.
/home/user/MyDocs # df -h
Filesystem Size Used Available Use% Mounted on
rootfs 227.5M 140.8M 82.5M 63% /

At this point I had installed Fennec and something was causing a problem with my internet connection so I restarted the phone which freed up some memory again!

I now have almost every useful app installed today and still have 92.8MB free!
~ $ df -h
Filesystem Size Used Available Use% Mounted on
rootfs 227.5M 130.6M 92.8M 58% /

I have been using the phone for 3 days since running Tom's script and it has been 100% stable.

Thought I'd post this to let people know that There is a safe script to take away the problems around Rootfs without risk as far as I can see!

Thanks again Tom, I will still check Rootfs before and after installing apps, but am not worried about it anymore!

Hope this gives some people confidence to safely free Rootfs space.

Also thought it was about time I posted something to the forum having used info from here so heavily since getting my N900.

Cheers

Steve
