I'm trying out Linux by installing openSUSE 12.2 x64 on VirtualBox; the host is 64 bit Windows 7 Ultimate. I gave the install 16GB of storage - I will only be messing around with it - I thought this should be plenty. By default, Virtual Box splits the storage you give it roughly in half - giving half to the rootfs and about half to user space.
I've figured out via previous attempts that when the rootfs partition gets full - nothing works. But I've hardly done anything with it - I've installed Linux, run some updates and haven't even installed any extra software. I'm seeing that my rootfs is filling up fast - 83% already with no extra software installed - and hardly anything is going to my other partition (/home).
Is this expected behavior? Does all installed software get installed to the rootfs? I've heard you should try to keep rootfs as small as possible, but all I've done is install Linux and update the system and it's at 4.8 GB - 83% full.
How can I keep my rootfs from filling up? Should I have adjusted the VirtualBox defaults to just make rootfs bigger?
Here's the results from a df: Notice how the /dev/sda3 is hardly used.
