I think this gives the new config files. I save the binaries that
emerge creates. I found the new bash and extracted the config files.
The ones that start with a number are in the bashrc.d directory. They
are attached.
I might add, after the update, I had issues with my PS1 and alias
settings. My main rig went rather well given it has been through a few
updates. The new rig however was like pulling teeth. I ended up
copying the /etc/bash directory from my main rig. Then it worked.
Using dispatch-conf and me rarely being able to use it correctly is
causing problems. I need to find a better tool. Thing is, I don't
think one exists. I'd encourage you to use the bashrc.d directory when
possible. That way your settings aren't mixed in with defaults.
Hope those files help.
