- I agree with Mark Brader. In response to the moderator's suggestion
- that "if you set the umask on your home directory to 022, and that were
- inherited through your directory subtree, you would get the same effect
- for your files as with a per-process umask," I would point out that
- this doesn't work for files in /tmp.
-
- [ Good point. Assume the old per-process umask still exists as a default,
- though. (I've been assuming that but haven't mentioned it.) If /tmp
- has no directory umask, things work. Most of the other objections
- are also accounted for. -mod ]
-
- My major objection, though, is that the proposal would break existing
- programs. For example, tar and cpio would have to be modified to
- handle the per-directory umask. This would mean new tar and cpio tape
- formats, which would probably be unreadable by existing versions of tar
- and cpio. I wrote a version of rcp a couple of months ago which would
- have to be changed. Programs as unlikely as ed and passwd would
- require modification.
-
- In my view, the benefits of going to per-directory umasks are
- outweighed by the disadvantages. I might be convinced otherwise with
- additional argument. But changes which are not backwards compatible
- must be justified by *major* benefits.
