Seems that all the dangling symlinks on my KDE VM are owned by RPMs.
I ran this to find this out the state of symlinks:
sudo symlinks -r / | grep dangling | while read A B C; do echo $B; rpm -qf $B; done | grep 'is not owned'
Thanks Barry. I have 3 dangling symlinks at the moment, and your script says they are not owned by any package. Not being owned is not surprising as all 3 are "lock files" for Firefox and Thunderbird both of which are not rpm installed, they are both upstream daily versions of the two applications. I was trying to understand the target of the symlink, which in the case of these 3 symlinks begins with my local IP address, being 192.168.1.109:+5960 (for firefox). So after a few tests it has become obvious they are making use of what seems to be standard Linux functionality, in that Linux allows the creation of symlinks linked to non-existent locations.
Right. That's an example of what I meant by an application storing text data in a symlink. Even if they were rpm installed, the lock files most likely won't be owned by the rpm.
In my view they are showing poorly designed software, I can understand the Thunderbird lock symlinks as Thunderbird is currently running, but Firefox is not running and it is configured to not continue running background tasks after closure (I think that option is in firefox). The firefox lock is in the profile folder, but I don't understand the purpose of the lock as its existence doesn't stop the folder from being deleted. To me the existence of that lock after shutdown is an indication to me that the developer was being lazy and not properly cleaning up on normal shutdown.

Steve
