+I've spent the last couple days fiddling with [Debian Bookworm
+RC2][bookworm] in a VM.  No issues to report.  It's shaping up to be
+a great release.
+
+I've been looking for a suitable [Docker][] replacement for a few years
+because of [their repeated license shenanigans][license-shenanigans].
+Last year I tried switching to [Podman][], but ran into into several
+incompatibilities and minor annoyances.
+
+[Podman 4.3][podman-4.3] ships with [Bookworm][] and seems to fix all
+the issues I had before.  [Rootless containers][], [multi-stage
+builds][multi-stage], and all of my muscle-memory `docker` commands now
+work as expected.
+
+The only real differences I noticed are:
+
+1. The command is `podman` instead of `docker`.
+2. Image names are registry-prefixed.  Example: `FROM docker.io/bash` instead of `FROM bash`.
+3. Searches are registry-prefixed.  Example: `podman search docker.io/pablotron`.
+
+A couple of quick tests:
+
+* [Sinatra web application (rootless)][sinatra-test]
+* [Go web application (rootless, scratch, multi-stage build)][go-test]
