udevd: failed to rename network device

[Ivan Suzdal]

We have race condition between setup-bootdev and udevd. In setup-bootdev we are run udevadm trigger which go to race condition with systemd-udevd service in some cases.

[Ivan Suzdal (isuzdal)]

During start services, systemd require sd_notify support for guarantee what service will started _only_ after another service was successfully started, we can to handle this in our setup-bootdev without adding support sd_notify.

Attaching part of /var/log/messages from the node where this error occurred. There are two files, both from the same node, failed one was found in a snapshot, and successful log was taken from the same node after a reboot (no other changes made).

[Dmitry Teselkin (teselkin-d)]

Just in case, content of /var/log from the same node
