embed userdata in update.zip and extract to folder during install


Hi guys - total noob to linux here.
I've been playing around with a linux update for XBMC on a matricom mx2 tv box. I've learned how to unpack the update - unsquashfs the usr.sqsh file (and re-squash) and finally how to re-pack and sign the update.zip.
I have been playing around with the updater-script but I don't really have a good idea how this update works.
Basically I would like to embed a folder called userdata into the update and extract that data upon install into a selected folder.
I'm sure this is a simple task, but I'm not even sure where such a command would be placed (in the updater-script?).
Any help you guys can give would be greatly appreciated - it's taking me ages to make quick changes - repack and sign - then load onto the box to test - and I'm getting nowhere fast.
Thanks in anticipation.
G.

Angry Am I looking in the wrong place?

Wow guys - I thought this was a total noob question but I haven't had a single response yet.
I can only assume that I am looking in the wrong place - perhaps this cannot be achieved through knowledge of linux?
If any of you guys can point me in the direction of where I might find an answer to this one it would be greatly appreciated.

Thanks in anticipation.

G.

this is what i am getting:
Code:
[schneidz@hyper ~]$ uname -a
Linux hyper 2.6.43.8-1.fc15.x86_64 #1 SMP Mon Jun 4 20:33:44 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
[schneidz@hyper ~]$ updater-script
bash: updater-script: command not found...
seems to be like some specific software you are trying to install/modify. have you asked over at the xbmc forums (since they wrote it some developer over there can probably provides hints of how to modify it).

this is not a generic linux thing that is normal.


generically speaking, this is how one would add a file to a zip-file:
Code:
[schneidz@hyper temp]$ unzip -l userdata.zip 
Archive:  userdata.zip
  Length      Date    Time    Name
---------  ---------- -----   ----
       12  07-11-2014 10:28   1.txt
       12  07-11-2014 10:28   2.txt
---------                     -------
       24                     2 files
[schneidz@hyper temp]$ zip userdata 3.txt 
  adding: 3.txt (stored 0%)
[schneidz@hyper temp]$ unzip -l userdata.zip 
Archive:  userdata.zip
  Length      Date    Time    Name
---------  ---------- -----   ----
       12  07-11-2014 10:28   1.txt
       12  07-11-2014 10:28   2.txt
       14  07-11-2014 10:29   3.txt
---------                     -------
       38                     3 files
