Package: nis
Version: 3.17.1-3+b1
Severity: important
Tags: patch
Dear Maintainer,
* What led up to the situation?
System has several lxd containers that run ypbind. When the system was
restarted (or even ran dist-upgrade just prior to restart), pybind failed
to start. I have determined this is because start-stop-daemon is confused
by processes named ypbind visible in the containers even though they are
not "local" and not accessible by the host system. I have also determined
that simply passing "--pidfile /var/run/ypbind.pid" to start-stop-daemon
-- as is already done for the stop case -- fixes the issue.
* What exactly did you do (or not do) that was effective (or
ineffective)? Manually running "ypbind" works, as does the above fix.
