Log message:
	Fix create_temp_name to replace any '/' found in the hostname with '?'.
	
	There's a possibility someone will use the '/' in the hostname. Since we
	generate a temporary file name (path) including the hostname, any '/' would
	be ambiguous.
	
	We can always set such hostname using 'sethostname' from unistd.h. But the
	'hostname' command already includes the check and removes the '/' char.
	However, some old versions still allow that.
	See: https://bugzilla.redhat.com/show_bug.cgi?id=711445.
	
	Since this is only a temporary name and the possibility of this error is
	quite negligible, we don't need any complex escape sequence here, just a
	simple char replace.

 Version 2.02.86 -  
 =================================
+  Fix create_temp_name to replace any '/' found in the hostname with '?'.
   Always use append to file in lvmdump (selinux policy - no file truncation).
   Propagate test mode to clvmd to skip activation and changes to held locks.
   Defer writing PV labels to vg_write.
