Personally, each time I get a message like this:
One or more symlinks to directories have been preserved in order to
ensure that files installed via these symlinks remain accessible. This
indicates that the mentioned symlink(s) may be obsolete remnants of an
old install, and it may be appropriate to replace a given symlink with
the directory that it points to.
I am unsure what I am expected to do. Should I remove them? For now I simply don't do anything but, if that is ok in most of the case, I am unsure if this message is useful enough to be recorded
Thanks a lot
