I've made my own initramfs to boot.
/boot is a separate partition with ext2, grub, bzImage and
initramfs
/ is ext4 on logical volume on encrypted container
[ext4:lvm:luks:sda2]
swap is on another logical volume, next to /
I used two links as hints to build it:
http://jootamam.net/howto-initramfs-image.htm
http://jootamam.net/howto-basic-cryptsetup.htm
It's important to have all libraries copied to initramfs or to make all
binaries static (ldd). Some time ago I had dropbear in initramfs to
help booting headless server. Watch out for pivot_root restriction of
PID == 1.
