Re: sri-unix.1410: redirection to file

There is a simple solution to the problem of keeping a protected
data file for use by a program, and still having the users of
the program able to write to their own files.  The program should
be run setuid to the owner of the protected file.  Within the
program, the first thing it does is open that file, and the
second thing is setuid(getuid()).  The protected file remains
open, but all further actions occur with the user's permissions.
Are you listening, esquire!psl?
