Tailscale for piCorePlayer

Packages and installs the current release of Tailscale as a piCore extension. Run it as tc on your piCorePlayer:

wget https://raw.githubusercontent.com/atdt/tailscale-picoreplayer/main/mktailscale.tcz.sh
chmod +x mktailscale.tcz.sh
./mktailscale.tcz.sh

On a fresh install, load the extension and authenticate:

tce-load -i tailscale
sudo tailscale up

After that, upgrade with:

tailscale-installer
sudo reboot

tailscale-installer is this script, copied into the extension and frozen at the version that built it. Re-download from here to pick up any changes since.

The current stable release is the default. To build a different one, or if the script can no longer work out which that is, name it:

TAILSCALE_VERSION=1.102.1 ./mktailscale.tcz.sh

https://pkgs.tailscale.com/stable/ lists the current version.

What it does

• Downloads the current stable release for your architecture.
• Builds tailscale.tcz and sets it to load at boot.
• Puts a copy of itself in the extension, as tailscale-installer.
• Starts tailscaled when the extension loads.
• Keeps the node identity on the pCP data partition, so it survives reboots.
• Can act as a subnet router or exit node.
• Survives pCP in-situ upgrades, including kernel changes.

Coming from a manual install

Several recipes for installing Tailscale circulated on the piCorePlayer forum before this package existed. If you followed one of them, the script picks your node identity up from wherever that recipe left it, so you keep the same tailnet IP without re-authenticating.

The extension starts itself, so remove whatever used to start it or the daemon will run twice: the pCP user commands under Tweaks → User commands, and any tailscaled lines in /opt/bootlocal.sh. Then run pcp bu.

Packaging the script as an extension

The build script can itself be shipped as an extension, so that loading it from a repository puts tailscale-installer on the system. mktailscale-installer.tcz.sh builds that, writing tailscale-installer.tcz alongside the .info, .list and .md5.txt a piCore repository expects. Run it as tc on a piCorePlayer:

./mktailscale-installer.tcz.sh

Acknowledgements

This started from the piCorePlayer forum thread. Checksum verification and keeping state out of the pCP backup are taken from mll's install_update_Tailscale.sh. Using --tun=tailscale0 in place of userspace networking was wetenschaap's suggestion. The tun driver behaviour and how third-party binaries ought to be packaged were explained by paul- of piCorePlayer.
