Kdyz uz takhle, tak radeji nejak takto

int
main()
{
  static char *argv[] = { "skript.sh", NULL };
  static char *envp[] = { "PATH=/bin:/usr/bin", NULL };
  return execve("/.../skript.sh", argv, envp);
}

Ovsem nejlepsi je se set[ug]id skriptum zdaleka vyhnout (nebo je psat
v Perlu, i kdyz suidperl... no.. ehm...). Tedy ono je obecne lepsi
se vubec set[ug]id programum vyhnout, protoze napsat takovy program tak,
aby nebyl reflektovan v pristi verzi baliku "rootkit", neni trivialni. :)
