Hello again,

I need a small follow-up help on this subject:

I threw out all generics from my system (at least I think I did), and 
most of the old lowlatencys as well, so that I'm now left with 
3.5.0-31-lowlatency and 3.5.0-33-lowlatency. That's what the advanced 
part of GRUB tells me, anyway.

Now the latest update wants to install "Header files related to Linux 
kernel version 3.5.0", new install, 12.1 MB.

To me this doesn't look like lowlatency, so I'm inclined to not install 
it, but how can I know for sure?
