For me to edit a file that’s within the root partition e.g. /etc/fstab , I am forced to log in as super user via File System Manager-Super User mode.I would like to copy my files to or edit files in my root partition without having to log in to my root partition as a super user so that it will be as easy to have read-write access to my root partition just like in my home partition.
How can I achieve this?Please respond soon.Thanks in advance.

I am aware of the security merits of a password controlled root partition has but my problem is as follows.
I have a very small home partition (only 1 GB) since my machine has both openSUSE 10.3 and Windows and my HDD drive is only 80GB.
My root partition has 5 GB free space
I would like to install software e.g. Oracle for Linux.Naturally I would want it to be installed on my freer root partition but during installation its default installation path is in the home partition.If I try to change the path to a root partition,I get the error message that I do not have rights to place my files on the root partition.Of course when I try to install in the default home partition,I get the error message disk full.
How thus can I install software from root partition?Please respond soon.Thanks in advance.
In addition to all the good advice given above I might throw in some remarks, because my idea is that you have some misconseptions. When I am wrong, I do appoligize.
The root partition has nothing to do with the user root (except for their shared name). The root partition is the disk partition that is mounted on /. And that is at the root of the Unix/Linux directory tree. You do not need a password to read and/or write there.
You do need the root password when you want to access directories/files that are not owned by you, but by root (and root not giving the allowance to do the r/w by e.g. setting the access bits for ‘world’).
Now when you have a seperate /home partition, most directories/files that are on the / filesystem are owned by root and not writable by normal users. This is because of ownership and access bits, not because of them being on the root filesystem.
Back to your problem.
I understand that your /home partition is getting full, but that your / partition is still having space enough. Apart from the tedious task of shrinking/expanding filesystems, a (maybe only temporary) solution might be found by using space on / for part of your user files and making a symbolic link to it.
Example. User happy is running out of space and gathers a lot of music file in /home/happy/Music/. We want to move this to the root partition so that more music can be added and also more space for others things becomes available on /home/happy/.
As root create a directory on the root partition and make happy the owner:
cd # to your home directory
mv Music /happy-needs-more-space/ #takes some time because it will copy all music
ln -s /happy-needs-more-space/Music Music #makes the link from your well know place to where it is now
And happy is back into bussiness.
I hope you get the principle behind it. Of course after this your root partition does contain userdata and this should be taken into acount when installing a new system.
A good idea would be to move your home directories into the root partition, unmount the old 1 GB home partition, delete the old 1 Gb partition, expand the root partition to take up the free space. That way the new /home directories can expand normally as you add files, securely accessing any or all available space on the expanded root partition.
You could do everything from inside the running openSUSE operating system except the final expansion of the root partition. You would need to use GParted on a bootable disk to expand the root partition.
You would not have to add or purchase any extra resources/storage.
If you decide to do that, you should take advice on a series of steps to achieve it safely.
