If your root file system is at the start then it is unlikely to be large 
enough to break any boot loaders.  Recent boot loaders are very capable...

chgrp log /var/log/*log
Set quota for log group.  Problem solved?

From what I've seen LVM is much better at breaking data into pieces than 
it is at putting them back together...  I wanted to take over maintenance 
of the LVM packages for Debian but couldn't because I couldn't get it
