.: Shell Replacement :.
If you ever wondered how to replace the default shell of your newly installed OpenBSD, this post might help you! :)
After you have configured your packages repository, just fire the commands bellow:
pkg_add -i -v bash
chsh -s bash root # this sets bash as the default shell for root
chsh -s bash gabriel # this sets bash as the default shell for the user gabriel
I think you've got the idea!
