Dependency hell is not exclusive to Fedora or RPM based distros.

I'd modify the interface of GetUpdates()  so instead of returning a
list of packages to be updated it returns two lists
- list packages that can be updated:
- list of packages that are blocked and what packages are blocking
[kernel, [kmod-nvidia, kmod-ntfs]],
Here the update viewer would grey out the kernel and hal-info packages.
 : Sorry, I haven't studied the interfaces in detail so I'm making
this up. It may be just be noise.
