Network device becomes unmanaged by going to multi-user target
Last modified: 2013-09-30 02:21:56 EDT
Description of problem:
A network device becomes not managed by simply switching to multi-user
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install F19-rc2 (I did it on VMware fusion)
2. Once the system is up and running, I set it to enable sshd, disabled the firewall. Then I changed it to multi-user with ln -s /lib/systemd/system/multi-user.target /etc/systemd/system/default.target and rebooted
3. After some time and one more reboot, the system came up without network and systemctl restart network.service fails, indicating that the device is not managed by NetworkManager.
The network should still be operational -- nothing changed in the network.
I did not change anything network-related in the time I used the machine (only a few hours). I only installed pungi and a few other tools and started to work on porting some RoR apps we have.
Here is a screenshot after going back to graphical target:
Upon review, I believe I changed (using the GUI) one thing on the network settings: I set IPV6 from Automatic to off and applied it.
I did notice now that the top-right applet for networking said "networking disabled". I clicked on it and the network started working.
