I used rpm-ostree to layer vim-enhanced and vim-X11 in Fedora Silverblue. The Vim Flatpak didn't give me console Vim, and Silverblue Vim wasn't picking up my .vimrc.
I have two Toolbox containers for Ruby in Fedora Silverblue, but they share the same files for gems. It has caused some trouble. Better to use Distrobox with a dedicated home, or rbenv/RVM.
Ruby is having issues with OpenSSL 3.0
