Nope, nowhere. I have only a few aliases set and that's it. Fedora
defaults always worked for me.

After reading the changelog for bash-4.3 and picking up the trail from
Adam Williamson's blog post and bug report up to the systemd-devel
list, it seems that indeed systemd is the culprit (or cgroups
notifications in the kernel, depending on who you might ask). Does
this warrant an interim solution (e.g. deploying the script with
prompt_command) until it is fixed? Should we let bash poc (Ondrej
Oprala) know about it?
