busybox 添加新命令

BusyBox v1.01 (2009.06.18-05:22+0000) multi-call binary

Usage: busybox [function] [arguments]...
   or: [function] [arguments]...

        BusyBox is a multi-call binary that combines many common Unix
        utilities into a single executable.  Most people will create a
        link to busybox for each function they wish to use and BusyBox
        will act like whatever it was invoked as!

Currently defined functions:
        [, addgroup, adduser, ash, brctl, busybox, cat, chmod, cp, date,
        df, echo, env, free, fuser, getty, halt, hostname, ifconfig, init,
        initmac, insmod, kill, killall, klogd, linuxrc, ln, login, ls,
        lsmod, mkdir, mknod, modprobe, mount, mv, passwd, ping, poweroff,
        ps, pwd, rm, rmdir, rmmod, route, setmac, sh, sleep, stty, sulogin,
        telnetd, test, tftp, top, umount, uptime, wget
这是我的busybox版本系统，当前系统没有crond与crontab命令，请问有那些方法可以添加新的命令到1.01的版本中，可否安装个1.81的版本，然后将1.81版本中crond与crontab复制到当前的1.01版本中去使用？？？


是否还有其它方法，小弟是菜鸟，在线等

    在编译 busybox 之前把你想要的配置上就OKay了。
