 closes SSH connections

With OpenSSH turned into inetd style in commit
808b9e850491c7b1d867a5f1f4d5ee6f61f345d4, the service upgrade code used
by ‘guix system reconfigure’ and ‘guix deploy’ wrongfully decides that
the ‘sshd-*’ transient services corresponding to individual SSH
connections should be closed:

I think the solution is to leave transient services untouched.

Unfortunately, the status sexp returned by ‘services->sexp’ currently
lacks information about whether a service is transient.

Fixed with:

  eeb8ac43c8 services: shepherd: Do not unload transient services.
  a2c759c830 services: herd: Report whether a service is transient.

Hm.  I'm getting this issue.  I did a guix pull locally, on the
server... doesn't seem to make a difference.  I get the very error
reported above when using "guix deploy".

I guess others aren't?  I wonder why I am...

I reopened this, because I'm hitting it on all the machines I use "guix
deploy" with.  I think, before closing, it would be good to hear if any
other guix deploy users are hitting it.  If it's just me, well I'll have
to figure it out then, but I suspect it isn't just me. :)

It’s been a year now :-) but I’m definitely not getting this issue (SSH
connections getting closed) when using ‘guix deploy’.

What about you?

Maybe we can close?

Thanks,
Ludo’.
