[Bug 1800719] Re: missing conf files noted on apt upgrade after distribution upgrade

[Jerzy Luszawski]

The files /etc/ld.so.conf.d/i386-linux-gnu_EGL.conf and
/etc/ld.so.conf.d/i386-linux-gnu_GL.conf are symlinks to
/etc/alternatives/x86_64-linux-gnu_egl_conf /etc/alternatives/x86_64
-linux-gnu_gl_conf, which are in turn the symlinks to
/usr/lib/virtualbox/additions/00vboxvideo.conf (from VirtualBox
package).

Update-initramfs seems to have problems with symlinks (why?).

Replacing the symbolic links with hard links (or just a copy of target file) resolves the warning, there is no need to remove the config files. 
Note that updates or reinstallation of VirtualBox will break the link, so this is not a permanent solution.
