From Gentoo Wiki
The unofficial sys-kernel/mkinitramfs-ll (found in tokiclover's bar-overlay) is a lightweight and modular variant of the previous well known initramfs generating tools which comes with udev free dependency. It depends only on busybox with mdev by default and depends on extra packages for additional functionalities. So, nor bash, coreutils nor util-linux is bundled into the initramfs. Extra flexibilities are offered as well, like the possibility to have DM-Crypt LUKS on top of LVM or vice versa, btrfs or ZFS on top of DM-Crypt LUKS, DM-Crypt LUKS on top of RAID, detached header (to a device or a file) for dm-crypt LUKS et al.
