cloud-init service is set to start before NetworkManager service starts,
18322d
but this does not avoid a race condition between them. NetworkManager
18322d
starts before cloud-init can write `dns=none' to the file:
18322d
/etc/NetworkManager/conf.d/99-cloud-init.conf. This way NetworkManager
18322d
doesn't read the configuration and erases all resolv.conf values upon
18322d
shutdown. On the next reboot neither cloud-init or NetworkManager will
18322d
write anything to resolv.conf, leaving it blank.
18322d
18322d
This patch introduces a NM reload (try-restart) at the end of cloud-init
18322d
start up so it won't erase resolv.conf upon first shutdown.

    cloud-init.service needs to wait until network is fully up before
2b0ae0
    continuing executing and configuring its service.
