I peeked a bit. Will this also handle debuginfo files that are directly installed on the filesystem?

Yup!

% dbgserver -F /path/to/base/directory

should find executables / debuginfo / corresponding sources

How does this ending up working on a normal desktop or server? Is the idea that there would be a systemwide dbgserver instance, perhaps socket activated, or maybe several instances?

As an admin, I would much rather *not* have a systemwide daemon for this, since that implies a path by which one user can attempt to attack another user or the system as a whole. I'd rather if each user could, on demand, start up their own instance of whatever libraries and programs are needed to make debugging work. Nothing here should require any form of privilege.

Any of the above.

Fair enough, though DoS is perhaps the worst of the possible attacks.

Right.
