I'm not sure at this point in time (I haven't looked at the source in a year or so). I know "install -C" preserves the last modified and probably the created time. > > > You don't blindly want to remove files and I doubt you want > > mergemaster to list possibly hundreds of files as removal > > candidates.

On slow hardware, "install -C" can significantly speed up a "make installworld", because the installworld doesn't have to copy any files from /usr/obj to some destination. I'm beginning to think a mtree.obselete is the way to go. Each committer, who deletes something from the base system, should be required to update mtree.obselete. I think we should also add a "make purifyworld" or a new mergemaster option should invoke the mtree.obselete to clean the tree. I normally use touch(1) and find(1) to eliminate cruft. -- Steve To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
