How to allow write access (create/write files) to a directory but prevent delete (to all, including owner)

rated 0 times [ 0] [ 0] / answers: 1 / hits: 2735 / 2 Years ago, fri, march 18, 2022, 11:21:02

I want to allow any write access to directory but prevent ANYONE (aside from root?) from deleting the files once they are written. Is there a permissions system that would allow for this?

There is no time to modify permissions between write and delete time.

chattr +a seems to work as it only allows append to the directory (creating files)

Root won't be able to remove it directly but is able to chattr -a when it comes time to delete.
