Discussion Thread
I would follow the suggestions in https://github.com/mkj/dropbear/blob/master/DEVELOPING.md for Deubg Printing, as this seems difficult to solve within information from dropbear.

Adding Computer Tracking (GPS)
Heads is good reference for what could be done at BIOS level. It can connect via ethernet but only because the firmware is built in (The GBE section in IFD stands for Gigabit Ethernet). If you want an SSH server, this needs to be built separately because Dropbear is too big to include by default. Due to the size of firmware and range of different wifi cards that could be installed plus the software to connect, wifi is not possible in Heads. Similarly with Bluetooth. For cellar, the firmware, software and configuration would be needed to BIOS. There is also how no service/roaming would be indicated without any physical meter like LEDs (Ethernet has LEDs to show connection). It would also take time during the boot cycle to connect to a cellular service and would block booting the OS. That said, you could add a service at boot of your OS to do this and connect to something like a NextCloud Phone Tracker to do this.

tinyssh
While it is good to have another alternative, I think Dropbear SSH[1] is also being used very widely.

Host a Dev Environment on Render with VS Code and Tailscale
I need an SSH server. I try OpenSSH, but run into an issue when I attempt to log in. OpenSSH servers use privilege separation as a security measure. The OpenSSH subprocess that handles authentication runs as an unprivileged user with its root directory set to some safe location. The CAP_SYS_CHROOT capability is required to change the root directory for a process, but Render services run in unprivileged containers without this capability. I discover that there are other SSH servers, like dropbear, that don't do privilege separation. This is great because it's not necessary for my use case anyway. My SSH server will run as a non-root user and will only be available within the VPN.

SSD belonging to Euro-cloud Scaleway was stolen,then turned up on YouTube
That's what Dropbear is supposed to do, it can be included in the initramfs of a server: https://matt.ucc.asn.au/dropbear/dropbear.html
Disclaimer: I still didn't try it myself yet, but it's on my (too long) list of things to do.
What are some alternatives?
When comparing render-dev-env and dropbear you can also consider the following projects:
docker-phoenix - A dockerized Phoenix development and runtime environment.
tinyssh - TinySSH is small server (less than 100000 words of code)
