I don't know, but maybe a script that checks if the link belongs to a package, and only removes it if it doesn't. But I'm not sure it's worth the hassle. (Especially that that output of symlinks is not very useful in a script. As far as I can see, one would have to extract the filename from it using a(n adimittedly, probably quite simple) regexp.) > (question 2) > In a later post, Andras provided and example of a dangling symlink (in > the "hunspell" package) that should not be deleted.

But it's not just hunspell. Far from it!
