Hi Guix,

I think this has been happening for quite a long time, but I never paid
attention to it, for everything seemed to be running just fine.
When I run `guix home reconfigure`, it completes with the following message:

```
# [=E2=80=A6]
Finished updating symlinks.

SSLoading /gnu/store/zbfyaxxigns5lqyxhxzxhm92w54ns1cz-shepherd.conf.
herd: error: exception caught while executing 'load' on service 'root':

nts and
          /gnu/store/2sr90smj33k686394krjx1klhlpipd7z-home/profile/share/fo=
nts... done (same)
Evaluating on-change gexps.

On-change gexps evaluation finished.
```

I don't know if it's related, but since my last `guix pull`,
`herd status` has been reporting strange statuses:

```
$ herd status
Started:
 + root
Starting:
 ^ mcron
 ^ mpd
Stopped:
 - tor
 - transmission
```

`mcron` and `mpd` (a home service that I will eventually submit) are listed=
 as
`starting`, but they are actually started and they work just fine!?

I had a look at this morning's log. This is what I see right after logging =
in:

```
2023-08-23 08:21:36 Starting service root...
2023-08-23 08:21:36 Service root started.
2023-08-23 08:21:36 Service root running with value #t.

2023-08-23 08:21:36 Starting service mpd...
2023-08-23 08:21:36 Starting service mcron...
2023-08-23 08:21:36 Service mpd has been started.
2023-08-23 08:21:37 [mpd] Aug 23 08:21 : server_socket: bind to '0.0.0.0:66=
00' failed (continuing anyway, because binding to '[::]:6600' succeeded): F=
ailed to bind socket: Address already in use
```

The last line is strange. It looks like a second instance of `mpd`
started, tried to bind to the same port and failed!?

After `guix home reconfigure` I get:

```
2023-08-23 08:31:51 Service mcron has been started.
2023-08-23 08:31:51 SSL2023-08-23 08:31:51 oading /gnu/store/zbfyaxxigns5lq=
yxhxzxhm92w54ns1cz-shepherd.conf.
```

There is no mention to `mpd` and there's a timestamp right in the middle of
the second line?!

When I try to `herd stop SOMETHING`, it hangs forever and I have to
`ctrl+c` it.

Any idea what might be going wrong?!

I experience the same thing. I hadn't updated guix since may (last generati=
on 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 di=
sappearance 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 worke=
d because the getenv wasn't evaluated immediately, but after a reboot the s=
yntax error prevented shepherd to start the session.

But once I solved that, same problems: shepherd seems to hang somewhere aft=
er starting the home services.

My 3 services are working normally. If I try to run `herd restart emacs-dae=
mon`, 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 `ho=
me-shepherd-service-type` in my home configuration (not just commenting %em=
acs-daemon-user-service and running it with an empty list of services), the=
n there is no error when running `guix home reconfigure`.

When reconfiguring with an home-shepherd-service-type service but not sheph=

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

Just throwing out that I'm also experiencing this issue, even with a 
home configuration containing a single service, that being 
home-gpg-agent-service. I've deployed the same configuration on two 
different machines at the same checkout and only experience the issue on 
one. The other machine works flawlessly. The only distinction between 
the two is that the working machine is using Guix on a foreign 
distribution while the nonworking machine is using Guix System.

I do see the same behavior mentioned previously such as herd commands 
hanging. However, in my case there seems to be another negative symptom 
from shepherd acting this way.

Various $ gpg commands will hang (presumably when they try invoking 
gpg-agent). Trying to manually invoke $ gpg-agent --daemon fails and 
hangs indefinitely without a message. This effectively makes gpg 
unusable.

Barebones home-environment:
--8<---------------cut here---------------start------------->8---

      (service home-gpg-agent-service-type
               (home-gpg-agent-configuration
                (pinentry-program
                 (file-append pinentry-tty "/bin/pinentry-tty"))
                (ssh-support? #t))))))
--8<---------------cut here---------------end--------------->8---

Interestingly when running $ gpg --card-status I see the following 
printed to the log:

For some reason shepherd is rereading its configuration file instead of 
properly spawning the gpg-agent service. shepherd.conf and 
shepherd-gpg-agent-ssh-agent.scm (a file that appears in shepherd.conf) 
are identical between the two machines.

shepherd.conf (working and nonworking machine):
--8<---------------cut here---------------start------------->8---

(action (quote root) (quote daemonize)) (format #t "Starting 
services...~%") (let ((services-to-start (quote (gpg-agent ssh-agent)))) 
(if (defined? (quote start-in-the-background)) (start-in-the-background 
services-to-start) (for-each start services-to-start)) (redirect-port 
(open-input-file "/dev/null") (current-input-port))))
--8<---------------cut here---------------end--------------->8---

Sorry if this is too much or not helpful! First time on the mailing 
list.

Did some more testing and I was able to find a workaround for my version 
of this issue, although I don't know if it'll solve it for others. TL;DR 
is I changed my login shell from fish back to bash.

The system configuration for the nonworking machine was using fish 
`(user-account (shell (file-append fish "/bin/fish") ...)`. There seems 
to be some unintended behavior with executing the `on-first-login` 
script in `.profile` using fish.

The stock `config.fish` sources $HOME/.profile, which executes the 
.guix-home/on-first-login script via fenv source $HOME/.profile. Herd 
seems to start up nicely, but somehow stdout for herd winds assigned to 
a pipe without a reader between initialization and spawning gpg-agent.

initialization writes to the logfile just fine regardless of if you're 
using fish or bash:

When using bash instead of fish, stdout (file descriptor 1) points to 
/dev/null so the write does not fail. Another write is for 
$HOME/.local/state/shepherd.log.

However, when fish is in charge of executing on-first-login, stdout and 
stderr for the user shepherd get directed to a pipe instead of 
/dev/null.

fish fds, both stdout and stderr point to a pipe:

Details of what processes are using the pipe: (i.e. nothing else is 
using the pipe. Which makes sense for a broken pipe error at least...)

--8<---------------cut here---------------end--------------->8---

What confuses me about this situation is judging from that bash behavior 
pipes shouldn't be involved at all for stdin/stdout/stderr. There's also 
an discrepancy in that stderr for bash points to xorg-session.log while 
for fish it points to the same pipe as stdout. It would be interesting 
to know if other users who are experiencing broken pipe errors are also 
using fish as their user shell.
