To get around the recent glibc version requirement on a Red Hat Enterprise 7 system, I'm running the Dropbox client in a Docker container with the Dropbox and .dropbox folders mounted externally on an Ext4 filesystem on the RHEL7 host. That's working fine currently.
Today I received an email from Dropbox informing me that I had to move my Dropbox folder being synched from the Docker container to an Ext4 filesystem by Nov. 7. Given that my Dropbox folder is already on an Ext4 filesystem, will synching continue to work for me on/after Nov. 7? I'm a bit perplexed as to why I received the email today.
Here are the relevant mount entries, as reported by the Docker container:
/dev/sda1 on /dbox/.dropbox type ext4 (rw,relatime,data=ordered)
/dev/sda1 on /dbox/Dropbox type ext4 (rw,relatime,data=ordered)
