# The configuration is based on upstart, which is in Ubuntu up to 14.04 LTS (Trusty).
|
||
|
|
# Ubuntu 15.04 and above replaced upstart with systemd as the init system.
|
||
|
|
# Consequently, the configuration cannot work on these images. In release-1.2 branch,
|
||
|
|
# GCI and Trusty share the configuration code. We have to keep the GCI specific code
|
||
|
|
# here as long as the release-1.2 branch has not been deprecated.
