Generally looks good, thanks for working on it and adding init support to hgctl, I do not want to block this for too long, so I would like leave a couple of follow-up tasks.

Improve UX

• opt install/uninstall/profile logs
• add logging animation/color
• support multi log-levels

Add waiting between components

• make sure components are running well.

Clean code
