config: Call hotplug hooks in more places #1233

Also add an ACTION environment variable containing the same value as passed as a command-line argument. Some scripts presume they will only be called in the one existing place so they need to be updated also.

You could also use fs.stat(filename, "type") == "reg" for this, no?

Mnyaaaa.. good question. I looked at this myself. Initially the function was just moving around existing code. When I looked at the general consensus on how to do this in Lua, I found the following:
"Using plain Lua, the best you can do is see if a file can be opened for read, as per LHF."
-- https://stackoverflow.com/questions/4990990/check-if-a-file-exists-with-lua
I believe "LHF" here refers to Luiz Henrique de Figueiredo, the creator of Lua.
So this is both in line with the Lua way of doing things, and it's what the existing code already does so I left it as is. That said, I'm certainly open to changing it to be more POSIXey but I was trying to do things in a Lua way because my Lua experience is very limited.

Good point. Both seems fine to me.

I suggest to switch to @pony1k suggested version as it is more compact and we already depend on those libraries

This function or something very similar feels like to be used/needed in more place in LiMe code, let's try to avoid duplication
