Yes, and that means that anything linking with libGL has a hidden dependency
on the ogl-select SMF service, which I doubt the packaging system can know
about without hardcoding that in.
As you may remember, the ogl-select author originally proposed the mount
point method, but LSARC made him change to this one, because they were unhappy
about the confusion and problems (like failure to build flash archives properly)
caused by the libc mount.
