But since there may be other problems than with "at", announcing
the change in the NEWS file would have probably be a good idea.
Things that an admin was usually doing may no longer work, for
instance (like some build as a normal user when possible, then
as root to install files). Now, concerning the symlinks, since
this affects just symlinks directly under /tmp (not those below
subdirectories), the effects are probably very limited.

I see that audit follow_link messages are generated in the kernel
logs when doing completion as root in /tmp, but everything seems
to be fine.
