Description William Hubbs gentoo-dev 2012-10-20 18:48:35 UTC
This is to track the service scripts which are using "need net"

Most of the time services do not really "need net", and this should be

The problem with having it is that bringing down one interface
automatically brings down the services that have "need net" in their
Comment 1 William Hubbs gentoo-dev 2012-10-20 19:12:25 UTC
To test your service to see if it really needs net, do the following:

- bring down *all* of your network interfaces, including loopback.
- drop the "need net" line from your init script.
- bring up your service in its default configuration.
- If it comes up successfully, try cycling network interfaces and using
  your service with different interfaces up and down. If it works, you
  are done; commit your init script without the "need net" dependency.
  - If it doesn't work, you will need to add documentation to your
	conf.d/service file explaining to users how to  tie your service to
	which ever interface they are using it on with an rc_need line.

Feel free to contact me with questions.

/etc/init.d/netmount is triggering NetworkManager (+dbus +....) to start without any "need net". Looks like a hidden "need net" in some dependency.
