Well, perl has "suidperl", maybe Python has something similar.
Otherwise you could make a small setuid wrapper around your script. It
only needs to be as simple as:
#include <unistd.h>
extern char **environ;
int
main(int argc, char *argv[]) {
argv[0] = "/path/to/khm.py";
execve(argv[0], argv, environ);
return (1); /* shouldn't get here */
}
Just compile that, make it setuid (root, presumably) and it should work.
I'll assume you already know the potential dangers of setuid programs.
