Well, this is not a bug but a question on the design of most Unix systems. It seams to me, and I tried this on Ultrix 4.3, HPUX 9.01, Linux 1.1.x, when root opens a file, being the owner or not, the system does not check the file permissions before granting him access. The same goes for writting and unlinking a file.
I've long considered this to be "wrong" as well. Forcing root to have to obey whether something is allowed to be writable by root would close up a lot of the various holes out there. Of course this creates problems with things like the traditional "passwd" program that would then have to know to do a chmod to give root write perms to the password file.. kevin -- kevintx () paranoia com || "Ask me no questions, I'll tell you no lies."
