Say I have an arbitrary number of directories, labeled by numbers.I also have the directory merge.I can domount -t overlay -olowerdir=1:2:50 overlay mergeto get the contents of 1, 2, and 50 in merge.What is the best way to 'add' more directories to the overlay, say, 23, 81, and 457 as if I had done the commandmount -t overlay -olowerdir=1:2:50:23:81:457 overlay mergein 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.
overlayfs with a lot of directories
