Can't you determine the uid at run time with code similar to the following?

    struct passwd * passwd_entry;
    uid_t           ups_uid;

    if (! (passwd_entry = getpwnam("ups"))) {
        fprintf(stderr, "user id `ups' does not exist\n");
        exit(EXIT_FAILURE);
    }
    ups_uid = passwd_entry->pw_uid;

It would make the program also more robust against changes in the uid 
numbering done by the system administrator.
