It seems to be that service extensions are not unloaded when removed
from the services that caused them to be loaded?

Thanks,

Maxim

Hi!

At the Shepherd level, there’s no notion of service extension.
Normally, after reconfiguring, “herd restart guix-daemon” (really
“restart”, not “stop” + “start”) should start the new service, which
doesn’t have all these ‘--chroot-directory’ options.

Note that the guix-daemon process you should seems to be a child process
(presumably because there was still a client running when you restarted
the service), not the main guix-daemon process.

You should check the command line of the main process, the one returned
by “herd status guix-daemon”.

HTH!

Ludo’.

FTR, I had used 'guix deploy' and issued 'sudo herd restart guix-daemon'
on the remote after it completed successfully.  Why should stop + start
be different than restart though?  That seems counter-intuitive.

You are right that this process has the correct arguments:

$ sudo herd status guix-daemon
Status of guix-daemon:
  It is started.
  Running value is 25628.
  It is enabled.
  Provides (guix-daemon).
  Requires (user-processes).
  Conflicts with ().
  Will be respawned.

$ cat /proc/25628/cmdline
/gnu/store/rqif4yxa6ny4nxrdq6whnva2r089jm0c-guix-1.2.0-13.a53f711/bin/guix-daemon--build-users-groupguixbuild--max-silent-time0--timeout0--log-compressionnone--discover=no--substitute-urlshttps://ci.guix.gnu.org--max-jobs=20

Some of the other process were apparently caused by 'guix 
environment' shells still running in screen; I've terminated them all
now and ran 'sudo herd stop guix-daemon'; surprisingly I still had two
remaining guix-daemon processes that were launched manually for testing
purposes.  That's on a Guix system with an uptime of 174 days and
counting :-).

Thank you for the answer and sorry for the noise!  It works as designed.

Closing.

Maxim
