To build a generic initramfs, you have to install the following software packages: * device-mapper * cryptsetup-luks * rpcbind nfs-utils * lvm2 * iscsi-initiator-utils * nbd * mdadm * net-tools iproute Generic initramfs'es are huge (usually over 10 megs in size uncompressed), but should be able to automatically boot any bootable configuration with appropriate boot flags (root device, network configuration information, etc.)
