/mnt/user/appdata vs /mnt/cache/appdata
With the understanding that 'appdata' is set to cache only, I understand that these two paths should be functionally identical, but I remember reading something in my early days of unRAID research "something something appdata user shares no-no", but can't find anything about it, despite google-fu.
Any reason I shouldn't use /mnt/user for appdata?
No issues with using /mnt/user/appdata vs /mnt/cache/appdata. You *may* however run into trouble if the same appdata was previously accessed via /mnt/cache/appdata instead of /mnt/user/appdata (or vice versa)
My philosophy is to always use user shares for appdata, and set them to be cache: prefer though. (I actually don't have any cache only shares at all) My reasoning is that I would prefer in the case of the cache drive becoming completely full for all of my applications to still remain
