This is great news. /usr/lib seems like an odd place, though. Does not seem to match the description in hier(7) (not that the man page can't be updated). Looks to me like it fits /var a bit better, though I'm not sure that much data is appropriate for many /var partitions. Still, wherever the symbol files end up, getting them out of root is something many people have wanted for a long time. -- R.
