Hi,

Today I connected to my laptop running guix home over ssh as the first 
session and got greeted with a lot of shepherd logs from the 
on-first-login script from guix-home starting the user shepherd:



Starting service root...
Service root started.
Service root running with value #t.
Service root has been started.
WARNING: Use of `load' in declarative module (#{ g107}#).  Add 
#:declarative? #f to your define-module invocation.

Some deprecated features have been used.  Set the environment
variable GUILE_WARN_DEPRECATED to "detailed" and rerun the
program to get more information.  Set it to "no" to suppress
this message.
Restarting signal handler.
Now running as process 2026.
Starting services...

Starting service dbus...

Service dbus started.
Service dbus running with value 2027.
[...]
Successfully started 4 services in the background.



As I don't want to see these messages I have patched the 
add-shell-profile-file procedure in gnu/home/services/shells.scm to send 
the output of the on-first-login-script into the void as a workaround.

The shepherd manual mentions a --quit option (there seems to be also 
--silent but not documented). Looking at the shepherd code though these 
don't seem to do anything which is also not mentioned anywhere causing 
even more confusion.

The guile deprecation warning seems to be coming from using the 
deprecated way of daemonizing the shepherd. This has been fixed in 
https://git.savannah.gnu.org/cgit/guix.git/commit/?id=8da4eab2447a52c1d4f79305756cfab4df45a1a7

The devel shepherd now understands --silent (and --quiet): 
https://git.savannah.gnu.org/cgit/shepherd.git/commit/?h=devel&id=6ffe404ffe794b06fddd304a963a47b62444edfa


When running the shepherd <at> 0.15 with a backported version of the above 
commmit and --silent all that is left is the warning

> WARNING: Use of `load' in declarative module (#{ g107}#).  Add
> #:declarative? #f to your define-module invocation.

and when using the devel shepherd this is also gone and shepherd is 
completely silent.


It would be nice to add an option to home-shepherd-configuration to 
autolaunch the shepherd with --silent once it is available in a tagged 
release.

I believe we can make this change right away since 0.10.x supports
‘--silent’ (it doesn’t have any effect as of 0.10.5 but it’s not
rejected).

Would you like to prepare a patch?

Thanks,
Ludo’.

Hi Ludo,

Thank you very much for the review of the shepherd patch and the patch 
for the silent? field to enable it.

Closing the original issue as well.
