Title: Crash upon empty result of piggyback hostname translation
Component: Checks & agents
Level: 1
Class: Bug fix
Version: 2.2.0i1
From Checkmk version 2.1 the
<i>Check_MK</i> service crashed if the settings in <i>Hostname
translation for piggybacked hosts</i> resulted in an empty host name.
The host name <tt>''</tt> is now replaced by
<tt>'_'</tt>.
This is consistent with other invalid host names (such as
<tt>'../../bin/pwn'</tt>), where the invalid characters are replaced
by an underscore.
