I am asking this because the > suggested root_fs builder The better thing if you really want to use UML to test it, is to built by your own a root_fs: - dd if=/dev/zero of=root_fs count=1000 bs=1024 (it is an example, custumize it) - mkfs.ext3 root_fs - mount -o loop /mnt/dir_root_fs root_fs - cd /mnt/dir_root_fs - debootstrap sarge uml http://ftp.debian.org/testing (if you come from debian world) - modify : /etc/inittab to have : 1:2345:respawn:/sbin/getty 38400 vc/0 not : 1:2345:respawn:/sbin/getty 38400 tty0 > http://umlbuilder.sourceforge.net/ > does not list a new distro like FC3 that I am using and it doesn't > look like having support for ext3.

No you compile _your_ modified kernel (with your patches on ext3) and boot it to a ext3 root_fs. > I just checked out QEMU and from the first look it seemed like vserver or Xen. Wow, I don't know vserver, but say that qemu is like Xen is a mistake. Perhaps I say mistake, so correct me. It is like this I can go on and improve. ~Christophe -- Kernelnewbies: Help each other learn about the Linux kernel.
