Package: tmux Version: 2.9a-3 If tmux is removed (but not purged) and then reinstalled the /usr/bin/tmux entry gets lost from /etc/shells. This is because the postinst calls add-shell only conditionally on first installs or upgrades from an old version which did not add tmux to etc/shells.
I guess the purpose is to preserve local configuration and give the local admin to the ability to remove the /usr/bin/tmux entry from /etc/shells. However, removing and then reinstalling a package is also supposed to preserve its configuration, so we are between a rock and a hard stone. :-( Looking at what other shells do, bash and dash behave the same way as tmux, but only really brave souls dare to remove either of those. On the other hand fish, ksh, mksh, rc, screen, tcsh and zsh call add-shell unconditionally.
