I thought it was easier to read being 3 different things, but if you prefer it to be 1 line, I can do that.

This does not look like a good idea why not having just one method with Once-initialization

I would like to, but that deep into the code, I didn't want to have to pass in the logger and the path to the executable. I wanted that to be set at startup and later usages of the manager, can get the singleton.

why are you stopping after restart is done?

Stop just disconnects the client from the socket, it does not stop the running daemon.

this all makes sense then :-)

can we check for errors here, if file exists but you're revoked access to it (too many fd, process reading/writing to it already whatever...) this will fail and we wont know

I will log it, but the error of not creating the listener socket will still be the really reported error.

Same as above, will log it.

Want me to add the path to the unix socket or the npipe?

no i meant talking to phrase feels weird to me

As above, this just disconnects from the running daemon.

i think what stop does and what i think it does are two different things

What does this PR do?
versionhas been changed to show both the version of the running daemon and the version of the executing binary. Along with--binary-onlyargument to skip connecting and reporting the version of the daemon and--yamlto print machine parsable version information.enrollhas been updated to connect to the running daemon and perform a restart. This is because after enroll if the daemon is already started it needs to be restart to load the new mode of communicating with Fleet.restartis a new command added to just trigger restart of the current running daemon. This is very useful to test re-execution (especially on Windows, because SIGHUP doesn't exist on Windows).This also includes some fixes that I thought was in my last PR for Windows, except I forgot to commit before merging the PR.
Why is it important?
To show the current running daemon version of the Agent, which could be different then the user executing binary. To improve the UX of the enroll command to re-start the daemon once successfully enrolled. To help debugging of re-execution.
