[Bug 1609110] Re: Do we still need the mesa or mesa-egl directories in /usr/lib/<arch>?

>the linux opengl abi requires that libGL.so is in
/usr/lib(/<multiarch>)

Does /usr/lib(/<multiarch>/mesa not count?

I also have it in /usr/lib/nvidia-364/libGL.so.

If this breaks existing things in some way I'm missing obviously that
wins out.

Title:
  Do we still need the mesa or mesa-egl directories in /usr/lib/<arch>?

Status in mesa package in Ubuntu:
  New

Bug description:
  One of our mesa changes means we can't sync Wine packages (or wine-
  development stuck in proposed) from Debian.  See bug:
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=827770

  We purposely end up creating in /usr/lib/x86_64-linux-gnu
  mesa/ld.so.conf
  mesa/libGL.so -> libGL.so.1.2.0
  mesa/libGL.so.1 -> libGL.so.1.2.0
  mesa/libGL.so.1.2.0
  libGL.so -> mesa/libGL.so

  Debian on the other hand just creates:
  libGL.so.1 -> libGL.so.1.2.0
  libGL.so.1.2.0

  I haven't found a clear reason for the divergence.  I do see some
  comments about making it work with the alternates system. I'm not sure
  if that's current though.  Long term libglvnd should help there in a
  better way (IIUC).

  For reference Fedora does:
  /usr/lib64/libGL.so.1
  /usr/lib64/libGL.so.1.2.0

  Can we drop these Debian differences from mesa for Yakkety?
