Maemo 4 does not have an ext3 partition on the built-in card so it's a no-go unless you repartition (at which point you are better off cloning the whole root).
Also, I have not analyzed your script, but be VERY careful about moving /usr/lib stuff around - that can cause serious breakage.

Thanks! So... which were the applications contributing to the load of your rootfs? Please share them here.

Well, according to the script itself, here's what I've moved:
libqt4-core 9,988k
hildon-theme-alpha 7,668k
nokia-maps-ui 6,876k
adobe-flashplayer 6,700k
nokia-maps-core 5,316k
nokia-maps-maplets 2,608k
I'll probably move more stuff as and when I need it - for instance, microb can be moved, and that will free up another 20 meg or so counting all its packages. Really, it should be safe to relocate anything wholly gui-based - so gtk, libpurple and so on are candidates.

Don't forget the eMMC is slower and also the device you swap to. From what I understand that's why originally Nokians did not optify qt and libs in general.

Yeah. But I'm happy with that as a temporary solution. It's improtant to remember that the right answer is to get packages optified properly.

ccooke, this is an (interesting) list of pre-installed packages but what I was asking was the apps you have downloaded getting your rootfs full.
You won't believe it but I'm asking this question to anybody here that gets in this situation and still nobody has given names of apps to follow and fix. It would be appreciated.

Going from memory, fennec/xulrunner were particularly bad, but they're long gone now. From the stuff that's still installed, the worst are (omitting smaller files for brevity) mplayer:
pc-connectivity-manager:
and bluemaemo:
BTW, this command:
can be used to show the top 50 space hogs.
Code:
-rwxr-xr-x 1 root root 8514264 Sep 17 22:43 /usr/bin/mencoder -rwxr-xr-x 1 root root 8683832 Sep 17 22:43 /usr/bin/mplayer
Code:
-rw-r--r-- 1 root root 4866193 Oct 20 21:04 /usr/share/maemo-pc-connectivity/manual.pdf
Code:
-rwxr-xr-x 1 root root 2018258 Aug 24 16:09 /usr/share/bluemaemo/themes/bluemaemo.edj
Code:
dpkg-query -W -f='${Installed-Size}\t${Package}\n' '*' | sort -n | tail -50

All times are GMT. The time now is 21:35.
This is a simple script that calculates which packages are taking up the largest number of blocks in /usr on the filesystem and can relocate portions of them to /opt. It does this in a safe manner - every operation is atomic and it will verify the files are identical before the final switch. It can also undo the relocation, if needed.
The first run will take ages - leave the device on power for fifteen minutes or so while it churns through all your packages and works out which ones use up most space in /usr. Subsequent runs will use a cache, unless you start it with the --clean option.
A few caveats:
* The script does *NOT* make sure /opt is in a sensible location. Make sure it actually is referring to a different partition!
* There's no blacklisting of packages. It *WILL* be possible to damage your system with this script if you relocate something that is needed before the partition holding /opt is mounted. Only relocate packages you believe to be safe! Anything you know you've installed yourself is a good bet, or anything which is entirely GUI based. The n900's nokia-maps app is a prime candidate. 'busybox' is *NOT*, even though it will probably be detected as the largest package.
* The script has been tested and works on my Ubuntu box and my n900. There is no reason it won't work for the n8x0 on Maemo 4 or Mer.
* Technically, there's a race condition when switching files, so I suggest everyone disables multi-user logins on their tablets and makes sure there's no malicious software installed. Or in other words: It's not really a problem in this case.
* The script will only relocate normal files in /usr. Nothing from elsewhere, no directories, links, special files, etc.
Use:
Get root on your tablet.
Make sure bash is installed.
Download the script.
