Shepherd doesn't use call/cc anywhere. However, it does use _delimited_ continuations, even though only through let/ec and 'guard'/'catch'/... More generally, call/cc is typically unused in (Guile) Scheme code, and call-with-prompt / abort-to-prompt / shift / reset / % are used instead. My guess what happens: the start code of a shepherd service fails between 'fork' and 'exec', with an exception. The exception isn't caught (or is caught and reraised), so the 'out' guard of the 'dynamic-wind' is entered and the file representing the socket is deleted. If that's indeed the case, it might be a good idea to install some exception handlers in fork+exec-command and friends (including make-forkexec-constructor/container), to make shepherd more robust w.r.t. services failing to start.

the systems seems to work fine. Gnome is up, i can log in with my user, and=
everything seems to work, except herd.
i encounter this broken state every once in a while. IRC logs also mention =
this multiple times, but without many insights:
https://logs.guix.gnu.org/guix/search?query=3D%2Fvar%2Frun%2Fshepherd%2Fsoc=

# uptime

```
looking at shepherd's code:
```
(define (call-with-server-socket file-name proc)
"Call PROC, passing it a listening socket at FILE-NAME and deleting the
socket file at FILE-NAME upon exit of PROC. Return the values of PROC."
(let ((sock (open-server-socket file-name)))
(dynamic-wind
noop
(lambda () (proc sock))
(lambda ()
(close sock)
(catch-system-error (delete-file file-name))))))
```
maybe this is caused by some call/cc magic that causes an unwind that delet=
es the file, but then continues?
