Re: Bug#1009712: sv: fails to control the service on Hurd

[João <phlogiston@sapo.pt>]

Hello,

Coming back to this bug.

I noticed that supervise/ok that sv is trying to open is a named pipe not a
file. I don't know if this is telling in some way.

I attach a more detailed debug log. Problems seem to occur in __dir_lookup.

Best wishes,
João
