Weird Dependancies? nmap, nc, etc.

[Justin Leapline]

Just was going about updating galera via the MariaDB repo, and it is requiring nmap and nc to be installed? Can someone tell me why?

nc and/or nmap are used in garbd init script (/etc/init.d/garb) for verifying that at least one node can be reached via given cluster address.
