Hi, I've just opened this: http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=128175 The bug is essentially about how we can sanely merge diskless[1] support into mkinitrd. Attached to the bug is a diskless-mkinitrd which is a separate mkinitrd script with diskless support. Just posting here so anybody who might be interested in the issue can jump in. Thanks, Mark. [1] - When I say "diskless", I mean that in the sense of a thin-client booting with e.g PXE and NFS mounting its root directory.
