choose one partition you want to install into.
if you installed new os on partition sda9, so you need change the /etc/fstab of the new os. like this:
/dev/sda9 / ext4 ...

the users's default password is loongson, and same does root.
sorry about that, i use another partition mounted as /home before i tarball the os, so you may need to add a new user to work.
i have changed the language to Deutsch and it dose work correctly, but because of my mistake, the tarball dose not have loongson-fc21 dir in it. the language configure file is located in user's dir, and as it dose not respond after you make the change in menulist, you need change locale language with steps:
1.locale -a to list all languages
2.change /etc/default/locale to LANG="en_US.UTF-8"

if there is no /etc/default/locale in os, you could add this line in /etc/profile:
export LC_CTYPE="en_US"

3.if it works, use the start menulist to find where to change the lang and wait for a while after click.

we have the live install iso, but only could install via network for now. 
i considered it may waste your time as the download speed is slow, so i tarball the os for you.
so sorry for that, and we will improve it.
