Funny observation: I decided that having a "/dummy" folder was a bit messy, so I umounted, and remounted using a dummy "/root/.aufs-dummy" folder instead.
After having done so, I am unable to remove the /dummy folder (rmdir: failed to remove ‘/dummy/’: Device or resource busy). Sensei, this reminds me of a previous issue, where I was trying to put the xino file on something not btrfs/zfs (remember?), and the folder became busy even when the mount failed. You found and fixed a bug because of that. I'm wondering if this might be related? Cheers :) ------------------------------------------------------------------------------ New Year. New Location.
