Concerns: Runtime image stage uses apt-get install libevent-2.* which is a glob and likely fails; should specify an exact package (e.g., libevent-2-0 or libevent-2-1) or rely on libraries installed by the tmux build., Consider ensuring /usr/local/lib is in the runtime's linker path; since tmux is installed under /usr/local, the container must be able to locate the libraries at runtime., Using the default CMD to launch tmux may not be test-friendly in all CI environments (tmux expects a TTY). Smoke tests should verify the binary exists and reports a version rather than trying to start an interactive session. Smoke [FAIL]: tmux -V Output: tmux: error while loading shared libraries: libevent_core-2.1.so.7: cannot open shared object file: No such file or directory Smoke [PASS]: command -v tmux Smoke [PASS]: test -x /usr/local/bin/tmux

Concerns: Stage 1 and Stage 2 use apt-get install libevent-2.* which relies on shell globbing; if no package matches, the install will fail. Use the exact package name(s) (e.g., libevent-2-1 or libevent-dev) or adjust glob handling accordingly., The runtime dependencies in Stage 2 rely on specific library names (libncurses5, libtinfo5). On very old Debian variants these packages may differ; consider pinning exact versions or validating compatibility with the target base image., No non-root user is created; running tmux as root can be a security consideration in some environments.
