I have a dual boot with one ubuntu distro on each (18 and 20). Each ubuntu boots on a different partition, and are not related in any way. Now I have created an empty small ext4 partition outside of the 2 distros. I would like to share this partition between my distros. What is the best way to do it?
Here is what I tried:
mount the shared disk onto each distro. However, the folder seems to be locked, as I cannot create a folder. I tried unlocking using sudo chmod 777 to unlock it from Ubuntu18. Then I log onto my Ubuntu20 and do the same. However, if I log back onto Ubuntu18, it seems to be locked. This is understandable since chmod provides access to one user alone.
