Adds a CLI subcommand that downloads a signed Tailscale appliance image (Gokrazy archive format, GAF) from pkgs.tailscale.com, constructs a fresh GPT-partitioned disk from it (mbr.img + a synthesized partition table + boot.img + root.img), formats /perm as ext4 in pure Go via go-diskfs, and ejects the disk so a user running on a regular workstation can flash an SD card or homelab VM disk in one command without installing e2fsprogs. On macOS the target disk is auto-discovered via diskutil, skipping the boot disk and anything bigger than 256 GB out of paranoia. On Linux the user passes --disk=/dev/sdX explicitly. Windows is not supported yet and the command returns an error. The GPT layout matches monogok's full-disk layout via the new public github.com/bradfitz/monogok/disklayout package; a drift- guard test inside monogok asserts the two implementations stay byte-identical so OTA updates against monogok-built images keep working. Behind a ts_omit_flashappliance build tag (on by default). Updates #1866 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com> Change-Id: Ic1a8cd185e7039edccb7702ab4104544fcb58d29

Private WireGuard® networks made easy
Overview
This repository contains the majority of Tailscale's open source code.
Notably, it includes the tailscaled daemon and
the tailscale CLI tool. The tailscaled daemon runs on Linux, Windows,
macOS, and to varying degrees
on FreeBSD and OpenBSD. The Tailscale iOS and Android apps use this repo's
code, but this repo doesn't contain the mobile GUI code.
Other Tailscale repos of note:
- the Android app is at https://github.com/tailscale/tailscale-android
- the Synology package is at https://github.com/tailscale/tailscale-synology
- the QNAP package is at https://github.com/tailscale/tailscale-qpkg
- the Chocolatey packaging is at https://github.com/tailscale/tailscale-chocolatey
For background on which parts of Tailscale are open source and why, see https://tailscale.com/opensource/.
Using
We serve packages for a variety of distros and platforms at https://pkgs.tailscale.com.
Other clients
The macOS, iOS, and Windows clients use the code in this repository but additionally include small GUI wrappers. The GUI wrappers on non-open source platforms are themselves not open source.
Building
We always require the latest Go release, currently Go 1.26. (While we build releases with our Go fork, its use is not required.)
go install tailscale.com/cmd/tailscale{,d}
If you're packaging Tailscale for distribution, use build_dist.sh
instead, to burn commit IDs and version info into the binaries:
./build_dist.sh tailscale.com/cmd/tailscale
./build_dist.sh tailscale.com/cmd/tailscaled
If your distro has conventions that preclude the use of
build_dist.sh, please do the equivalent of what it does in your
distro's way, so that bug reports contain useful version information.
Bugs
Please file any issues about this code or the hosted service on the issue tracker.
Contributing
PRs welcome! But please file bugs. Commit messages should reference bugs.
We require Developer Certificate of
Origin
Signed-off-by lines in commits.
