.so files in ReadyNAS NV+ root

Hi there,

Well stuff has changed around here. The old link brought in a new home. Looks good here. Nice.

Still running my ReadyNAS NV+ to the max. Still working fine. Update the firmware and stuff last week. But I noticed new files popping up in the root of the NAS. They have the extention .so. I think they are related to the new update, but just want to make sure.

Content of  the files are similar to the text below.
