Say I have an arbitrary number of directories, labeled by numbers.
I also have the directory
I can do
mount -t overlay -olowerdir=1:2:50 overlay merge
to get the contents of
What is the best way to 'add' more directories to the overlay, say,
457 as if I had done the command
mount -t overlay -olowerdir=1:2:50:23:81:457 overlay merge
in the first place?
If I want to "unoverlay" a certain directory, say
23, can I do it without unmounting the entire thing?
Conceptually, I guess you could say I want an arbitrary number of directories on the same "level" of overlay.
