I have used an aufs root before on gentoo years ago, but cannot seem to get it going now. I am using genkernel-next, I would imagine I used genkernel before as well.
I am using funtoo with aufs-sources and have aufs built-into the kernel (not a module). I believe I need to make some initramfs changes + command-line and /etc/fstab changes as well, but can't seem to figure out exactly what.
Any ideas?
aufs-sources
for the hardened sources entryfstab
