In the current osstest production this is at the end of:

preseed_hook_command($gho, 'late_command', '', <<END) if $gsuite =~ /wheezy/;

i.e. it is only done on wheezy (since it is a workaround for a Debian
specific issue).

So you need to add another use of preseed_hook_command to add your new
command.

I'm not sure what this will output, but I expect it has far too many
spaces between "," and "setting".

e.g. 
print("AAA
       BBB");
produces:
AAA
       BBB

I think you need to close and reopen the quotes and paste the two
together with . or, better, just leave the log message unwrapped
(wrapping also breaks grep...).

Ian.
