In this case, initramfs is your root filesystem, from which you load another fs and then transfer (pivot root?) to it. You have to build initramfs support into the kernel, to boot an initramfs. So my argument still stands, regardless of whether your *INITIAL* filesystem is ext4fs, or ZFS, or initramfs, that *INITIAL* filesystem has to be built into the kernel. Also, I really wonder what the point is in having to use initramfs on a system where /usr is part of /. -- Walter Dnes I don't run "desktop environments"; I run useful applications
