There IS a dual boot solution!

If you are, like me, in this situation:
partition 1: osx 10.3
partition 2: osx 10.2
(or the other way arround)
There IS a solution to unmount the 10.3 partition when you are working in 10.2 via the Terminal.
This will stop for instance a double clicked text file trying (and failing) to open in 10.3's Textedit...

notes:
- of course the 10.2 part should not have important references on the 10.3 partition. This won't be unless you created this yourself. It could be for instance that you linked your /Users of 10.2 to the 10.3 disk. Then you don't have to try this.
- after a reboot everything will be normal (and mounted) again. Wich is actually what i think you want...(safety) But it means you'll have to unmount again after reboot.

First check what you have to unmount:
open the Terminal and type:
df -l
In my case i get:
Filesystem 512-blocks Used Avail Capacity Mounted on
/dev/disk0s10 48973328 37642552 10841048 77% /
fdesc 2 2 0 100% /dev
/dev/disk0s9 29164992 13187152 15977840 45% /Volumes/OSX
I want to unmount my OSX disk, because this one contains 10.3, so /dev/disk0s9,
I type:
hdiutil unmount /dev/disk0s9
THAT'S IT!

To mount again you have to do:
hdiutil mount /dev/disk0s9
It will actually give a respond saying the disk is mounted on
/dev/disk1 /Volumes/OSX (in my case)

This actually means that if you want to unmount it again, you will now use:
hdiutil mount /dev/disk1
If your not sure anymore wich disk to unmount, just use
df -l

Good luck!
 
I do a reply on myself, because i have a question.
I made a simple application that i put in my startup items of osx 10.2 wich, does this all for me (now by 3 buttons, 1-open terminal and give the command "hdiutil unmount /dev/disk0s9
", 2-quits the terminal 3-quits the app itself).

I'm curious to see if the people with 2 partitions have the same 'standard' names /dev/disk0s9 (zero-s-9) and /dev/disk0s10
You can test this both in Jag and Panther by typing
df -l
in the Terminal.

If there is consitancy, i will make the little application safe for all systems and downloadable on my website, so that you can use it to.

Thanks a lot!

My system has 3 partitions, one is /dev/disk0s9 (has OS 9), 2nd (non-bootable) is /dev/disk0s10, 3rd (Jag partition) is /dev/disk0s12 (!)
So a hard setup would not work in my case
 
Why is all this necessary? I simply dragged the Panther partition to the trash to unmount it and it accomplished the same thing.
 
Ehm.. yes, right.. :)
Your're right..
Well, i'm happy that i at least i can make this thread that since i installed 10.2.8 (i was in time..) the problem is GONE! Files will now open in the right application, the same for the icons in the dock!
 
No, no, no. The easiest way is just to change the permissions on Panther's application folder to 0. In the terminal, and in the root of the Panther partition:

sudo chmod 0 Applications

This will make the Applications folder unreadable by Jaguar, which will then not know about the applications inside.

When you're ready to boot back into Panther, just open the terminal again, make your way to the root level of the Panther partition, and type:

sudo chmod 755 Applications

That's it! You can then leave all of your partitions mounted.
 
But.. Just wait untill the 10.2.8 is avialable again, as i said, it takes away the whole problem at once.

You won't need to do anything anymore..
in other words, files will now open the way you want to, without unmounting or chmod-ing at all!
