2.Download the pacth needed by reiserfs

gunzip all.diff.gz -> all.diff
3. cd /usr/src/linux   # actual directory may vary, of course
patch -p1 <XX/all.diff #where is the file all.diff
4.
make mrproper
make menuconfig # turn reiser4 on.
make bzImage modules
6. install kernel
7. download libaal, unpack, and build it
    $ cd libaal
    $ ./configure
    $ make
    $ make install # may require root
    $ # add /usr/local/lib to /etc/ld.so.conf if not already there
    $ /sbin/ldconfig # may require root
http://thebsh.namesys.com/snapshots/LATEST/libaal-0.5.0.tar.gz
8. download reiser4progs, unpack, and build them
    $ cd reiser4progs
    $ ./configure
    $ make
    $ make install # may require root

9  reboot with new kernel
10. create reiser4 file system

    $ /usr/local/sbin/mkfs.reiser4 -qf <path-to-device-or-file>

问题是，系统安装的时候没有reiserfs4啊，等到装完了，升级好了内核和软件，要升级到reiserfs4，又要重建文件系统，这个怎么解决？

BTW: I just want to try in /home /dev/hda9 (reiserfs V4 and /dev/hda8(just reiserfs V3) is my system root /

我在gentoo下面发现一个很好的东东——convertfs，可以在ext2 reiserfs jfs minix之间任意转换分区格式，这下把magic转换到reiserfs可方便了，只要修改/etc/fstab，然后unmount之后convertfs就好了……

I don't know.I don't want to try,neither.
Now I just mkfs.reiser4 /dev/hda9 and mount to /home.

数据安全第一，呵呵

不管怎么样，备份先，然后转换换格式，成功了就可以把备份的数据删除了……
