busybox sh support

Discovered On May 18, 2026

Primary Metric open

It seems that `bash` is the only supported shell. Is there any plan to support other shells? I have this running inside a busybox based kvm guest on linux/x64 and would like to be able to use busybox sh instead of bash. Am happy to work on a patch to support this if you think it would be desirable.

Not the OP, but I think that would be a quite valuable patch. One of the big selling points of this project is that, since it's so tiny and easy to compile statically, you can stick it in a whole host of places where ordinary systems may not tread.

In this case, it makes sense to support also [dash](https://git.kernel.org/pub/scm/utils/dash/dash.git), which is the default and very lean shell on debian and ubuntu.

It should simply be a configurable value instead of a hardcoded string, I guess.

Thanks, will add as configurable in v1.2.0 (later today, together with some TUI improvements)
