Inotify not working properly, failing to watch when running jekyll serve

[bluefantail]

I'm not 100% certain whether this is an issue for here just yet, but since I can't seem to find a scrap of info about this bug anywhere I figured I'd see what people thought.

I can't get a basic jekyll serve to run with --watch without it complaining about .git/hooks with

Invalid argument - Failed to watch "/mnt/c/Sites/jamiemackman/.git/hooks": the given event mask contains no legal events; or fd is not an inotify file descriptor. (Errno::EINVAL)

I can run jekyll just fine with --no-watch, or --force_polling.

Any ideas?

jekyll s -t --verbose

Gives me:

Hi bluefantail,

Thanks for your interest in WSL. Our inotify support is very limited right now, unfortunately.

This is a duplicate of #216

Ah thanks for that, I missed that issue.
