Hello everybody, I have just started working with overlayfs, and ran into a problem. Specifically I wanted to overlay the root of my filesystem with a command like the following: # mount -t overlay overlay -o lowerdir=/,upperdir=./tmp-upper,workdir=./tmp-work ./merged However, I noticed that my nested btrfs subvolumes and boot partition were not included in ./merged. I quickly learned though that you could have multiple lowerdirs. So next I tried the following command (I have a nested btrfs subvolume at /home, and my boot partition mounted at /boot): # mount -t overlay overlay -o lowerdir=/:/home:/boot,upperdir=./tmp-upper,workdir=./tmp-work ./merged I was expecting that now I would have (for example) the following directories: ./merged/home/$USER ./merged/boot/grub However I instead had: ./merged/$USER ./merged/grub Which shows that all the lowerdirs are placed right at the root of the mergedir. So I have two questions. 1. Is there a (easy) way say "I want to include all nested mountpoints into the overlay in their same directories"? 2. If there is not a (easy) way to do this, do you think it would be both feasible and useful to add such a feature? If the answer to question 2 is "yes", then I would be happy to take a try at this :) -- Nicholas B.
