fithis code is from a klik app ( Klik).
this code enable to run an app that is not in a normal prefix(/usr /opt) and enable to use the librarys from alot of paths.
basicly this code enable the use of cf and sd packages without the need of links(which consume alot of memory and is very slow and based on bash which is slowwwwwww!!!).

fithis code should be cleaned alot and should be run in the boot time.
this way you can run apps from cf and sd without the need of links to the root partiton which means no ipkg-link in the boot time(takes about 10 minutes on my Zaurus with alot of apps) and uses almost all the mem(from 30Megs in login to 2 Megs after a while).
i highly recommend to use this as it is more fast,low memory use and a simple solution

[pgas]

Though you can surely avoid a lot of links with this script, I'm pretty sure you will still need some.

For instance, what about an application that tries to load a conf file in /etc/?
emacs looks into a pretermined place to find its elisp library
matchbox looks into /usr/share/applications for the .desktop files.
What about the icons that applications expect to find in /usr/share/pixmaps?

I don't think a solution as generic as ipkg-link is easy to find.
Maybe a filesystem like unionfs...

[rmrfchik]

Haha, today, on my way to office I though about klik in Z. Klik's applications distributed as a single file with cramfs and can be run directly from this file.

I think klik (or other klik-like technology) should be discussed as way to distribute/use the apps under pdaXrom.

Sash, what do u think?

[urielka]

/etc is kept on root partition coz it doesn`t consume so much space!
to make it clear:every thing that is consider configuration should be on the root partition.

Thanks Urielka for those scripts.
Nevertheless I will ask you to make them a little bit clearer for me.
I have tried the second one and it seems to run without any negative message, BUT, no chage is perceived. I run it after "login" and before launching the X's. Is that O.K.? When I look at the free memory after launching KDE, I see that I've used almost 60 Mb. or RAM, so the SWAP is needed.
Regarding the first script, I've tried it to launch an application, "korganizer". So I have changed
the name of the program. Afterwards I receive a message of not having the close bracket at line 93. I have installed PERL to run it. I find also a problem with "ldd", but I have used the one that I have in Debian, and it seems to run.
The result is the same as with the second script: the application runs but with no differences with the usual way of launching it.
Your figures are so excellent that I'm sure I'm not doing things o.k.
Any help?

the script is not mine but i will try to write it ok once i restore the nand flash to my C1000(i erased it ,now i need to do a flash restore but i can`t find my card reader to do so  ).
in the end with my script you should not run ipkg-link at all(you can test it as moving ipkg-link to ipkg-link_notinuse or so so it will not run as you insert a card).
this also means that you willn`t need to install kde-striped-symlinks(if you use the good script).
plz don`t use this script if your level of bash/linux is not above 3-4 years of use(so you don`t fucked up your system).
just give my a few days and i will show the concept.
Sash and Laze ,are you interset in this?

[pgas]

Sash and Laze ,are you interset in this?

What about the problems I mentioned?

You say configuration files should be put in root, so people packaging application should put a postinstall script to move the configuration file to /.

What about applications with hardcoded link to images, data and the rest?
Should we put these on / too?

What about the C3000 where the root space is very limited?

Have you tried to use ruby emacs kdepimpi microemacs xmms tuxpaint  .... installed in /mnt/card with your script?

Should we check every application for hardcoded path and issue patches so that they read /etc/ipkg.conf and search for the files in every destination?  
 
A lot more work will be required when porting and packaging applications.

I don't say that a script like this doesn't work for some application and is not usefull, but it is not a solution as simple and as generic as ipkg-link.

[urielka]

i can`t test anything right now coz my Z isn`t working right now i need to reflash it and i can`t find my card reader.
ipkg-link maybe works for anything but it is slow and non-efficent.
ipkg-link runs after installing a application(if the application is on cf or sd) so if we change ipkg-link it can do all the post-installing things like the /etc and stuff.
we can also have some symlinks but it will be good to have the minimum of links.
most of the app have a VARIBALE that can be change to change the hardcode stuff.
packaging will take abit more but the we get a symlinks-free system.

[pgas]

ipkg-link runs after installing a application(if the application is on cf or sd) so if we change ipkg-link it can do all the post-installing things like the /etc and stuff.

You can allready add preinst,postinst,prerm,postrm scripts to the ipkg package

most of the app have a VARIBALE that can be change to change the hardcode stuff.

At compile-time, not at runtime:

See what is said on the klik site:

Making your application "relocateable"

Most Autoconf/Automake projects use hardcoded paths.

Because klik does not use traditional filesystem paths, your application will run best if it does not use absolute paths like /usr. In order to make existing application run, klik today patches binaries to convert absolute to relative paths. While this works for some applications, it is only a temporary solution and you should clearly try to avoid absolute paths in your application altogether.

[urielka]

give my all packages that you find them difficult to use with the script.
so i can test everything and maybe bring a better solution.

[pgas]

try these:

dillo ruby emacs kdepimpi microemacs xmms tuxpaint opie-reader every other application that have some files in /usr/share, or /usr/lib/

See what could be done (repackage, hack ipkg) so that the applications icons are shown in the menu.

Take into acount that /mnt/card and /mnt/cf, /mnt/user are not the only possible destination, on 3100 /mnt/hdda or something, theorically every destination in /etc/ipkg.conf are.
