I want to store lots of (valuable) additional metadata about my files in
the tracker database.

However, I am a little bit concerned about the safety of this
information. Apparently, tracker deletes everything that is associated
with a given file if it can't find the file itself.

Is there a way to make tracker keep all the information in the database,
even if the file temporarily disappears?

This is not possible, for file (system) resources

I'm worried about network failures, disconnected external drives,
accidental renames of the directory etc.

Disconnected external drives are handled,

How can Tracker (reliably) detect if a resource is on an external drive?
I can't believe that this works for anything but the trivial case where
/dev/sdX is directly mounted. But if the disk is e.g. LUKS encrypted,
then there's already a device mapper in between. It get's even worse
with all the possibilities that FUSE and bind mounts offer.

HAL (or devicekit) has a unique ID for each removable device. We detect
and use this unique ID for this purpose.

If you can't believe this, why don't you try it?
