Termux is a great tool, I've been using it to manage servers via SSH for years! Termux itself uses packages recompiled to work under Android, and uses proot jails to run other Linux distros, kind of comparable to docker containers.

This is a bit different than the proot jails used with termux and tools like AnLinux though. This is a running atop a KVM hypervisor, comparable to something like virtualbox on the PC. This will give better performance and security, and enable running a wider variety of operating systems, not just Linux.

Both are valuable tools, and have different benefits and drawbacks. 🤙
