I see. Thanks for explanation.
Anyway, I do not think setuid'ing luit to non-root is useful, and I do
not think disabling it does any harm.
I thought as I wrote in the previous mail because I was looking at
intro(2) manpage on Solaris, which said:
| Saved User ID and Saved Group ID
| The saved user ID and saved group ID are the values of the
| effective user ID and effective group ID prior to an exec of
~~~~~~~~
| a file whose set user or set group file mode bit has been
| set (see exec(2)).
This is different from the manpage on SUSv4, and I wonder what POSIX
is after all.... :)
Best regards,
