Describe the problem to be solved
When updating a plugin the plugin will be unavailable during the installation. We're storing all our plugins at s3fs, which means it takes 15-60 minutes to update.

Describe the solution you would like:
Let the plugin be available during the whole installation.

Describe alternatives you have considered
Install in the new version in tmp folder and just do a quick switch when it's done.

An easy solution could be to have the following file structure:

storage/plugins/latest (symlink)
storage/plugins/[checksum of package.json]

So the latest folder is always stable, and the symlink will change after update. Any opinions, @Chocobozzz ?

I'm sorry but I'm not sure I want to maintain this particular use case. Plugin installation/updates should be quite fast (a few seconds). If it takes 15-60 minutes on your system, I don't think s3fs is the appropriate tool to store PeerTube server files (including plugins).

I know s3fs is a bad solution for such case, and we will switch do a disk. But even a few seconds is bad for us, especially if something goes wrong with the update and the plugin will be unavailable for a longer time.

The use case is that we've a plugin that exposes an API that is critical in some apps that we're developing.

We've left s3fs now, but still it's not ideal that the plugin gets uninstalled during updates. With the solution below we should be able to skip the decache functionality used today.

An easy solution could be to have the following file structure:

storage/plugins/latest (symlink)
storage/plugins/[checksum of package.json]

So the latest folder is always stable, and the symlink will change after update.
