What's going through /usr/lib + changing my symlinks?

[Russell Sears]

I have multiple versions of libvorbisidec.so installed on my FR (updated 
factory image) for testing.

Every time I reboot, something resets the symlinks in /usr/lib.  It 
seems to take the name of the symlink, find all the files whose names 
begin with the symlink's name, sort them, and then update the symlink to 
point at the last one.

Why isn't this done by opkg update on a per-package basis, or at least 
system-wide at the end of each opkg run?  The current system is 
confusing (to me) and potentially slowing down boots.

Is there documentation of this behavior somewhere, or a relevant thread 
in the mailing list archives?  I did a google search, but might be using 
the wrong keywords...

Thanks!
