I have used it, for instance, for protecting artifacts published to a develpment archive server. I use incron to monitor the directories where artifacts can be uploaded, and as soon as an upload is completed, then incron invokes a call to 'chattr +i' to make the new file immutable and thus protect it from being overwritten by a subsequent upload or deletion.
Because it can also simply log accesses, reads, etc., it will probably do exactly what you want. Regards, -Roberto -- Roberto C. Sánchez
