Just noticed in my ~.kde4/ folder three new folders (all links) all ending in ".site"

~/.kde4/socket-username.site
~/.kde4/cache-username.site
~/.kde4/tmp-username.site

obviously these are just dups of the same folders that do not end in ".site", is this a bug or a new standard that will be replacing the same folders without the ".site"?

The ".site" name is from your computers hostname.
This likely occurs when your computer is either not connected to, or has just been, connected to a network.

You can see your current hostname by running "hostname".
The ".site" is the default domain SuSE uses I believe.
