I tried openSUSE 11.2 in Vbox and had a nice install. Then added some repositories, Packman etc. that was also passable. But the package management is Stone Age and difficult for me to understand.
For instance to get the Guest Additions in Vbox is terrible. There is no dkms package, one needs to install kernel-syms and kernel-source packages (ensuring that they match the kernel of course ..uname -a)
I tried this in Software Manager via Yast>Available. However once I had them selected for install and clicked Apply, I had to abort because Yast SM. wanted to install all the new packages from the added repositories - nearly 1 GB. So I tried Add/Remove Software, selected the kernel-syms package corresponding to the kernel (there were dependencies), and clicked Apply. After about 400MB I aborted that as well.
None of this nonsense with CentOS which is also much faster, and of course Ubuntu rules as regards package management.
I know that openSUSE is for intermediate users, so maybe I have not 'ripened' enough to use it properly.
My conclusion, nothing special, unintuitive package manager. Not good for me as I need to actually use a distro for my daily tasks rather than wondering how and why to accomplish tasks.
