+* What is =debuginfod=?
+- Relatively young (@@latex:$\sim$@@2019) project started by Red Hat.
+- It @@latex:\emph{@@"is a client/server [...] that automatically
+  distributes =ELF= / =DWARF= / source-code from servers to clients
+  such as debuggers across HTTP"@@latex:}@@.
+- The goal is to replace the need for =.dbgsym= files (but it can do
+  more than that).
+
+* How does it work?
+- There's a =debuginfod= server (e.g., at
+  https://debuginfod.debian.net) that indexes all available debuginfo
+  from several distributions (=unstable=, =testing=, =stable=,
+ =experimental=, etc.)
+#+BEAMER: \pause
+- Debugger-like tools (e.g., =GDB=) link against
+ =libdebuginfod=, which provides the client support.
+#+BEAMER: \pause
+- When the tool needs a certain debuginfo, it will contact the
+ =debuginfod= server (specified via the =DEBUGINFOD_URLS= shell
+  variable) and put a request for the debuginfo's =Build-ID=.
+#+BEAMER: \pause
+- If found, the server will then transmit the information over HTTP(S)
+  to the client.
+
+* How do I use it?
+:PROPERTIES:
+:BEAMER_OPT: fragile
+:END:
+- =GDB= on =testing= / =unstable= / =bullseye= supports using
+ =debuginfod= when searching for debuginfo.
+- Unfortunately, it wasn't possible to include automatic support for
+  our service on =bullseye=.
+- But don't despair! This is all that the user will have to do:
+
+#+ATTR_LATEX: :options frame=single
+#+begin_src bash
+export DEBUGINFOD_URLS="https://debuginfod.debian.net"
+#+end_src
+
+* Demo
+- Fasten your seat belts, please.
+
+* Future plans
+- Make it an official Debian service (ongoing task with the DSA).
+- Index and serve debuginfo from https://snapshot.debian.org.
+- Find co-maintainers (current bus factor: 1).
