Can running "sudo snap refresh" require reboot?

I have some snaps installed.

If I run “sudo snap refresh”, is it possible that I will have to reboot? I believe running “sudo snap refresh” will never require a reboot. Correct me if I am wrong. I am not an expert, I am an user. I think running “sudo snap refresh” is always supposed to be restartless.

And if reboot is required how will I know that?

I use Ubuntu Trusty. When I need to reboot because of running “sudo apt-get update” and then “sudo apt-get upgrade --with-new-pkgs”, there is a GUI popup telling me to reboot. If you want to see the popup program it is called “Software Updater”. You can start “Software Updater” by opening a terminal and running “update-manager”.

As the resources shipped in the snaps are not shared with the system, it should be unnecessary to reboot the system after refreshing snaps.

What if “core” or “core18” gets updated? Can you give me a link to the official notes on this?

If the core snap is updated only the snapd daemon is required to restart IIRC.

I don’t know if this is mentioned in any of the official docs, this seems to be an architecture design issue to me.
