yes, you are right, but remember that if you set up the network connection and you have got an Internet access, you can easily upgrade your root_fs to whatever recent distro.

Next step is to make this file a filesystem: for instance, if you need a ext2 filesystem, you must: # mkfs.ext2 my_filesystem Then you need to fill it up with the OS: # mount -o loop my_filesystem /mnt # debootstrap sarge /mnt http://ftp.debian.org/debian > > to create my_filesystem, I cannot boot UML with it. then unmount /mnt # umount /mnt and run linux: $ linux ubd0=my_fylesystem umid=test root=/dev/ubd0 ... and whatever other option(s) you need to. > I always got some error information like what I got in the > previous email. How can I create a filesystem just like those downloadable > from sourceforge? I am sure that you will be able to do the same with the other distros. Try it and if you will fail, please report all the command you type, ok?
