No, termux isn't a container, it's running directly in userspace on the host. The only weird thing is that because it's running directly on the host, it has to be built to use unusual paths, eg. /data/data/com.termux/files/usr/bin/bash instead of /usr/bin/bash. If it used containers (which IIRC it can't because Android doesn't really support it) that would actually be easier because then it could use a chroot to make the paths look normal.

Ah, well that stinks a little. I guess it makes sense, if android doesn't mandate a few kernel settings then working with containers might not be an option.

Couldn’t it implement a “fake chroot” by e.g. creating its own libc which wraps the real one but with path remapping, and then linking all its executables against that?

		That would only work for things that use libc (so eg. most Go programs are probably not going to work). The main way that you can do an unprivileged fake chroot is proot, which termux does offer - see https://wiki.termux.com/wiki/PRoot - but that has a significant performance hit.
