A question on setting setuid bit
I am building a package in which one of the binary has
to have the setuid and setgid bits set. I wonder which
one of the following two is the more appropriate method
1. Use "install -m 6755 <file> <dir>" in the install
target of the Makefile.
However, I already tried this method and it did not
work. The "install" program that I am using is part
of the GNU coreutils. I could not find any specific
confirmation that the setuid and setgid bits
(i.e. the first digit "6" in the numeric mode
"6755") can be used with the install program (the
document says only that the -m switch works "as in"
2. Add a "chmod ug+s" command in the postinst script.
