Thanks for the interesting link. Just one minor nitpick (I can't help myself 
)
On a compressed filesystem, this might be misleading because the "4k block" has only a virtual existence and doesn't reflect the actual disk usage associated with the file. At least as I understand it.
You can see this below. ls shows the file size (1 byte) whereas du shows (what it thinks is) the disk allocation..
~# echo > testfile
~# ls -l testfile
-rw-r--r-- 1 root root 1 Dec 22 12:18 testfile
~# du -h testfile
4.0k testfile

"du" however reports the actual size of the files

Hi,
thanks for the long list of non-optified applications. There is a list in the wiki where the applications should be added to track which are already optified for which are already exististing bug reports and so on:
http://wiki.maemo.org/Opt_Problem/Non-Optified_packages
For example fennec/firefox and vagalume are optified after reporting and a lot of other developers which are contacted are aware of the problem and will optify their packages.
Thank you,
Uwe

"du" does NOT follow symbolic links, i just tested it.
btw, -P is the du-switch to deactivate symlinks, but it's not present on the tablet, and it's supposed to be default anyways.
what makes you say that du follows links? any hard evidence?
What I did is:
I put the perl script on my device. I run it:
Code:
ssh root@mydevice mentionedPerlScript.pl /var/lib/dpkg/info/*.md5sums > /home/user/apps/nonOptified.txt

I confirm the "du" behavior.

Ok, here's an amended version of the script which tries to check for symlinked directories (by parsing the output of ls -l .. yuck!) ... recursively and with caching. May well be full of holes.. feedback welcome
I've put the extension as .txt to allow file-upload.
Edit: I've also updated the original script where first posted between [code] tags, above.

Code:
if -l $file
i'll give your script a go a bit later when i have more time.

for parsing the target of a link, there's a dedicated command available: readlink
Code:
~ $ readlink /opt /home/opt

Thank you for the rework. Also thank you for the effort you invest (script size doubled).
Unfortunately I still see some issues
(and I still did not learn perl ).
The mc package (which I moved away and linked it) seems to be handled correctly now. Thank you.
But now I just saw the following thing.
Report from the actual script version; from your original post (which I used):
So I guess there are more filesystem checks needed. Because for me it looks like the addblock-plus reported by the script are not on rootfs. For me "optified" means more "not on rootfs" than in a specific directory. Maybe thats where my problem comes from ^^.
But I would tend to say adblock-plus-1.0 is optified, though it is not in /opt.
Sorry for that trouble

http://www.linux-mtd.infradead.org/f...ml#L_df_report
"df" only reports the physically allocated memory and does not account for the compression that's taking place.
"du" however reports the actual size of the files, and not their compressed, physical size.
Thus, "du" will always report a higher usage than "df".
