In an private cloud EHC (EMC Hybrid Cloud) implementation there was a need that deployed hosts needed to have, well a hostname with a domain, like hostname01.example.com but the problem was that EHC does not support that in that version (as stupid as it sounds) so the developer put a script in all Linux templates called /root/hostmame.sh (yes with an error) which was run by cron every minute and the only thing it did was to put the hostname01.example.com into the /etc/sysconfig/network file (RHEL/CentOS/Oracle Linux) and to invoke the hostname command with hostname01.example.com as an argument.
Every minute of every host on the private cloud ...
... but I have come upon many strange problems in various EMC products so that does not surprise me a lot.
