To make konqueror regularly or by demand "scan the whole filesystem" is
possible? Is that a hard task?
The easiest and probably best way is to somehow have strigi index the inode number. The other way would involve a kded module or an entirely new daemon. Showing a different icon for files with more than one inode, and using strigi to look up the other names, would make sense.
Yes I trust my OpenBSD, but not blindly.
Makes perfect sense, particularly since OpenBSD is a really security-oriented BSD distribution.
I am building an OpenBSD-KDE distro.
And I want to know why it's storing those GB files hard-linked to
different subfolders (in such way that I can't know via standard KDE
tools what is the real space left free on my box, that this is YES a
matter of issue for me.
Do you know why they aren't using soft links? They'd be easier to manage, for sure. It's also easier to archive a system with soft links as opposed to hard links (e.g. cp -R and tar -c give you multiple copies of the same file).
