Bug#311597: anyterm and /bin/login in etch

[Julian Gilbey <jdg@polya.uklinux.net>]

Just discovered that in etch, /bin/login is not suid, which makes
anyterm useless.  The workaround I used was (I'm sure not totally
securely, though):

In the anyterm.conf apache configuration file, I gave
/usr/sbin/anygetty the  "--loginprog /usr/sbin/anylogin"  option, and
made anygetty setgid to anyterm (a group created by addgroup --system
anyterm).
Then /usr/sbin/anylogin is owned by root:anyterm with privs 4750,
compiled from:

#define REAL_PATH "/bin/login"
int main(int ac, char **av)
{
  execv(REAL_PATH, av);
}

HTH,

   Julian
