I'm using zsh, and I don't want to have bash installed, I don't think I'm the only one, but portage and dialog (in my case) depend directly on bash, but both perfectly work with zsh, and should with other shells, I think it will be a good idea to create a shell-config, in order to be able to choose which shell to install/uninstall
actually, our init scripts etc require bash.
I apologise for this bugspam, but I wish to close this product, so I need to move all the bugs.
