These changes add the ability to specify that a UFS file/directory cannot be unlinked. This is basically a scaled back version of the IMMUTABLE flag. The reason is to allow an administrator to create a directory hierarchy that a group of users can arbitrarily add/delete files from, but that the hierarchy itself is safe from removal by them. If the NOUNLINK definition is set to 0 then this results in no change to what happens normally. (and results in identical binary (in the kernel)). It can be proven that if this bit is never set by the admin, no new behaviour is introduced.. Several "good idea" comments from reviewers plus one grumble about creeping featurism. This code is in production in 2.2 based systems |
