Auto restart after power down

MySQL & MariaDB Percona XtraDB Cluster 5.x
1

I know this question has been asked many times, but has not found the answer.
According to [url]http://galeracluster.com/documentation-webpages/restartingcluster.html[/url]
galera cluster cannot survive power down and require manual restart (IDENTIFYING THE MOST ADVANCED NODE).

Is it true for Percona cluster? Is there any solution? What happens in case when 3 nodes automatically starts after power down?
It is not a problem for me to lose information written in last seconds, even minutes. More important is fully automated installation. Thanks!

Alexey, in recent Galera versions that come with Percona XtraDB Cluster, there is new option - pc.recovery, which may be something you are looking for:
