which version of nbd-server is that ?

I'll poke it.

pavka@pavka:~$ dpkg -l | grep nbd
ii nbd-client 1:2.9.6-1ubuntu1 the Network Block Device client
ii nbd-server 1:2.9.6-1ubuntu1 the Network Block Device server
ii nbd-server-dbgsym 1:2.9.6-1ubuntu1 debug symbols for package nbd-server

since nbd-server runs from inetd here we should just add an /etc/default/nbd-server file to the package and have a FROM_INETD (or so) variable in there.

source that file from the initscript and exit if the variable is set.

Poked into this tonight. Turns out a variable is dereferenced when it's not being set. I've patched the source, and hobbsee was about, and has uploaded a patch. We'll see if the autoclose magic works....

After upgrade here is in package wrong config file:

By default, nbd-server comes shipped with a pretty empty config file. Personally, The error really isn't appropriate, it isn't that there's something WRONG with the config file, just that there's no stanzas in the config file that nbd-server wants. The error is bogus, and nbd-server simply exits, as it's supposed to. Personally, I'll talk to Wouter upstream, and see if I can get the error message changed to something a little less frightening. Something like "No configured services, exiting." or like that.

Cheers,

I think, this package isn't shipped with a empty config file, but with wrong file. Ive problem with right configuration, because /usr/share/doc/nbd-server/ don't contains documentation and in man page istn config file overwriten too. Perfect error message will be path to right documentation or is possible add to package example config file.

pavka@pavka:~$ sudo cat /etc/nbd-server/config
[generic]
# If you want to run everything as root rather than the nbd user, you
# may either say "root" in the two following lines, or remove them
# altogether. Do not remove the [generic] section, however.
        user = nbd
        group = nbd

# What follows are export definitions. You may create as much of them as
# you want, but the section header has to be unique.
pavka@pavka:~$

that was fixed long ago i think ...
