If your copying app isn't selinux-aware (tar is, for example: it can store and regenerate the labels after the files are created), then the key point is, is the new file "created" in the new directory? If so, no matter how, then it will get a label based on the directory hierarchy it was created in, and that is usually "the right thing". rsync is definitely creating files in situ so it will normally not cause trouble. Doesn't matter if the source is local or remote, the label is decided at file creation time at the destination. -Andy -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
