Ubuntu versions prior to 16.04 always returned a successful exit status,
even if one tried to down an interface that does not exist. This
behavior changed in Ubuntu 16.04 to return an error. This commit
preserves the old behavior.
Fixes GH-7155
Refactor and repair regular expression attempting to match present interfaces.
The refactored regular expression will match on enp* ens* eth* variants.
Previously, configuring and enabling network interfaces failed with:
"The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!
/usr/sbin/biosdevname --policy=all_ethN -i bash: /usr/sbin/biosdevname:
No such file or directory
Stdout from the command:
bash: /usr/sbin/biosdevname: No such file or directory"
The previous attempt to fix this (ccc4162) doesn't work since it doesn't
properly parse the 'bash: /usr/sbin/biosdevname: No such file or
directory' error message.
This patch works around that problem and adds a comment explaining the
meaning of the return codes.
Currently `configure_networks` guest cap configures NICs following the device order and fails
when the device order is mixed. We should detect the appropriate NIC by its MAC address.
Windows offers no out-of-the-box rsync utility. By far, the most
commonly used external utilities for Windows rsync are built with the
GNU Cygwin libraries. The cost for this convenience is that rsync on
Windows has to be provided paths that begin “/cygdrive/c” rather than
“c:/“ like other Windows-API utilities. Compounding the situation,
rsync doesn’t create paths/to/sub/targets and so the vagrant plugin
code, when performing an rsync, is responsible for creating
intermediate directories in guest paths if there are any. Furthermore,
the mkdir utility in Windows is not another Cygwin utility like rsync
but the routine mkdir of Windows command.com. Therefore, while rsync
needs the /cygwin paths, mkdir uses the Windows paths. Later, the
chef_solo.rp provisioner running within the guest will expect to find
Windows-style paths in its solo.rb configuration file. Due to all this,
vagrant has to keep track of both the original, possibly dirty Windows
guest path and the cygwin-scrubbed guest path.
