I experience the same thing. I hadn't updated guix since may (last generation
was commit 91bfd30ee3f35dfb7048bf42aea92f939cffbf17), and since I did I'm
encountering issues with shepherd.
Probably unrelated, but for the record: my first issue was caused by the disappearance of the
XDG_LOG_HOME environment variable. I was using it in the definition of shepherd services (as for
example `#:log-file (string-append (getenv "XDG_LOG_HOME")
"/emacs-daemon.log")`. Guix home reconfigure worked because the getenv wasn't evaluated
immediately, but after a reboot the syntax error prevented shepherd to start the session.
But once I solved that, same problems: shepherd seems to hang somewhere after
starting the home services.

My 3 services are working normally. If I try to run `herd restart
emacs-daemon`, the command hangs until I press Ctrl-C and nothing happens to
emacs. Same thing for the other services (and for `herd stop`).
Here's how my services are defined. If I comment out all occurrences of
`home-shepherd-service-type` in my home configuration (not just commenting
%emacs-daemon-user-service and running it with an empty list of services), then
there is no error when running `guix home reconfigure`.

So I would guess it's a problem in home-shepherd-service-type, and not in the
custom service definitions. I also remember the broken pipe error showing
previously, but shepherd commands hanging is new.
