Several improvements to the gokrazy appliance build and flash workflow:
gokrazy/build.go:
- Round Pi image size up to a power of 2 (QEMU raspi3b requires it)
- Use monogok's mkfs.Perm for the /perm ext4 partition (pure Go,
cross-platform, no e2fsprogs dependency)
gokrazy/mkfs:
- Accept optional PermFile entries to include in the freshly-created
ext4 filesystem (used for breakglass authorized_keys)
- Use progresstracking.Ticker for flush progress reporting
gokrazy/tsapp*/config.json:
- Point breakglass at /perm/breakglass.authorized_keys (not ec2)
- Fix Pi SerialConsole to serial0,115200 (not ttyS0)
cmd/tailscale/cli/configure-flash-appliance.go:
- Add --add-ssh-authorized-keys flag to write an authorized_keys
file into /perm during flash (for breakglass SSH access)
- Use progresstracking.CountingWriter + Ticker for write progress
Makefile:
- tsapp-build-and-flash-pi: auto-include ~/.ssh/id_ed25519.pub
- tsapp-qemu-pi: use virt machine + UEFI + ramfb + e1000 (working
network + framebuffer), with DTB watchdog patch and
gokrazy.log_to_serial for debugging
- Auto-detect UEFI firmware path across Debian/Homebrew/Fedora
