/bin/bash all the things. Since we are using bash syntax in some of the element fragments, we should make sure we use bash for all of them, so that things don't break on systems where /bin/sh != /bin/bash.

Add element to run DHCP on all network interfaces. Ensures that all network interfaces are present in /etc/network/interfaces. Any interface not already defined there will be added and configured for DHCP. Change-Id: I27e0902e62804e8d719acd7288109bd0e294fd16 2013-03-05 17:34:19 +00:00

Rename generate-interfaces-file.sh... Rename generate-interfaces-file.sh to dhcp-all-interfaces.sh so that it is easier to find/remember in the $PATH on a deployed image. Also, on some distros the script actually generates many files so the previous name was a bit confusing.

Implement dhcp-all-interfaces for systemd. Includes: * Enhancements to the generate-interfaces-file.sh script so that it generates ifcfg network-scripts for distros like Fedora/RHEL. * Includes a new dhcp-all-interfaces.service systemd script which ensures network interfaces get generated before the network service starts on Fedora. * Add a new disable_interface function to generate-interfaces-file.sh which (on Fedora) will delete the ifcfg config for an interface which isn't plugged in. This is important because ifcfg-eth0 exists by default and we want to remove it if the NIC isn't connected. Previous behaviour on Ubuntu is unchanged and the generate-interfaces-file.sh just logs it as skipped. * General doc updates... I tested this on a multi-nic machine w/ Fedora where the first NIC exists but was not connected. Change-Id: Ia99e312539da43caefd72aa60398d43dac5dcc8f Closes-Bug: 1239880 2014-01-09 20:32:52 +00:00

Conditionally add dhcp-all-interfaces If the /etc/init drectory gets created on Fedora, it causes os-svc-daemon to add upstart init scripts instead of systemd. As a result none of the openstack services can start.

Support adding DHCP interfaces one at a time. Refactors dhcp-all-interfaces.sh so that if an optional INTERFACE argument (the first argument) is passed to the script it only inspects that single interface. If no argument is passed then the previous default behaviour is used which causes all interfaces to be inspected. To avoid a collision with the previous $1 we move to using $FLOCKED for the exec flock command which runs on distributions using ENI. Also sets PATH so that the commands within the script can all be found if it isn't set properly (/sbin/ip, /bin/cat, etc.) This is a move towards using udev rules to add these types of interfaces automatically.
