Hi saladin
No. It seems that was the problem. I was loading from an outdated onboot.lst. Thanks!
The tmux.tcz entry is all you should need in your onboot.lst file. The tmux.tcz.dep file lists the dependencies that the system
will load when tmux is loaded, including ncurses.tcz. That is of course if you are using the tools provided by Tinycore to
load extensions, and not manually downloading them yourself.
