Thank you for the certificate.

I've tried to launch the swarming bot, but I came across this error:

$ luci_machine_tokend -backend luci-token-server.appspot.com -cert-pem plan9-386.crt -pkey-pem plan9-386.key -token-file=$HOME/lib/luci_machine_tokend/token.json

Is there something I'm doing wrong?

Also, since we can't run Python on Plan 9, the idea is to run the swarming bot on a Linux machine, which will run the command on a remote Plan 9 instance (like ssh glenda@plan9 ls /).
Can the swarming bot be used this way? Maybe there is a similar approach to run the Go tests on Android.

Thanks.

Here is an update of how far the swarming bot goes currently.

I don't have the API error anymore. The swarming bot is starting successfully, then waits forever.
After 4m, it tries to restart the machine.

$ export SWARMING_ALLOW_ANY_USER=x

Thanks for trying again and confirming the API error isn't happening by now.

Did you have a chance to see your bot at https://chromium-swarm.appspot.com/botlist while it was connected, and what dimensions it reported? (Most relevant is the cipd_platform dimension.)

The attempted "Periodic reboot" seems unexpected, SWARMING_NEVER_REBOOT being set in the environment should've disabled it as I understand. For completeness, what's the version of bootstrapswarm?

bootstrapswarm is the latest version from the golang.org/x/build repository.

I can see the bot successfully on https://chromium-swarm.appspot.com/bot?id=plan9-386.

cipd_platform is linux-amd64, which is expected, since the goal would be to run the bot on a Linux machine and send remote commands to the Plan 9 machine through SSH.
