chattr +a would be perfect if it only applied to the root of directory, not everything from there on.
Is there a way to limit chattr to just the one folder (e.g. the opposite of -R as is normally required to perform actions recursively)
I tried changing permissions for the owner (root) but it seeemed to be of no avail, perhaps because I was root?
So suppose I have a directory that needs to be undeletable, but everything within it, I want to be able to edit, remove, and create new files.
Everything on, ugh, Google applies to non-root users chowning it to root, or else manually editing each and every file, extent and future. None are ideal solutions.
