  2. Fix getpwuid_r error handling 

    from man getpwuid:
"In case of error, an error number is returned, and NULL is stored in *result."
Error returned, NOT -1 and errno.
Example from man:
if (result == NULL) {
    if (s == 0)
        printf("Not found\n");
    else {
        errno = s;
        perror("getpwnam_r");
    }
    exit(EXIT_FAILURE);
}
