接着搞，往ramdisk里塞文件
现在是opensparc系统上的网络连不上，只能通过ramdisk上传下载文件了。
这玩意是个gz结尾的文件，在OpenSparc的文档上说要用Solaris系统的lofiadm命令加载。
解压gz文件，得到ramdisk.ubuntu-7.10-gutsy文件。
u@unamed:~/prjs/sparc64_ubuntu7.10_ramdisk$ file ramdisk.ubuntu-7.10-gutsy
ramdisk.ubuntu-7.10-gutsy: , boot block present
不熟悉ramdisk，随便搜了个方法试下。
u@unamed:~/prjs/sparc64_ubuntu7.10_ramdisk$ mkdir temp
u@unamed:~/prjs/sparc64_ubuntu7.10_ramdisk$ chmod u+rwx ramdisk.ubuntu-7.10-gutsy
u@unamed:~/prjs/sparc64_ubuntu7.10_ramdisk$ sudo mount -o loop ./ramdisk.ubuntu-7.10-gutsy temp
[sudo] password for u:
u@unamed:~/prjs/sparc64_ubuntu7.10_ramdisk$ ls
ramdisk.ubuntu-7.10-gutsy temp
u@unamed:~/prjs/sparc64_ubuntu7.10_ramdisk$ cd temp/
u@unamed:~/prjs/sparc64_ubuntu7.10_ramdisk/temp$ ls
bin boot cdrom dev etc home initrd initrd.img lib lib64 lost+found media mnt opt proc root sbin silo.conf srv sys tmp usr var vmlinuz
还真的可以了。不知道能不能往里加文件，反正是可以拷文件出来了。
回头sudo umount temp然后再gz打包，不知道行不行。
用这个参数让ramfile可写，sudo cp进去文件。
u@unamed:~/prjs/sparc64_ubuntu7.10_ramdisk$ sudo mount -o loop,rw,sync ./ramdisk.ubuntu-7.10-gutsy temp
先来个/bin/login和/lib64/libc-2.6.1.so。
这个libc要lib64里的，和之前sparc_ubuntu7.10.iso里的libc-2.6.1.so对比了以下，居然不完全一样。 不过strcmp看起来应该是一样的。

看上去也是8个字节读到寄存器里然后cmp，也就是subcc来比较。
