- I'm probably the only one in the Next sys admin world who didn't know
- this, but I found out the hard way that the FileViewer apparently strips
- the setuid permission when copying files even though it retains all other
- parts of the permissions matrix. The "hard way" I mentioned involved an
- attempt to restore /NextApps and /NextAdmin from the NS3.0 CDROM using the
- FileViewer (while logged onto root). Everything was copied exactly except
- the setuid permissions (there are 11 such files in /NextApps and
- /NextAdmin). This "stripping of setuid" occurs even if you copy a file
- from one part of your own account to another part.
-
- Ok. Now I know. I should have used cp -rp to restore the directories. Too
- bad. I've gotten real fond of using the GUI to do "Unix stuff".
-
- Is there any way to make the FileViewer copy the setuid permissions
- faithfully (like a dwrite or something)? I checked as much documentation
- as I could and found no mention of this.
