Yep, FAI is using a stock Debian kernel, which includes some
hooks/plugins for initramfs. We use the live-initramfs packages that
add some script into the initrd.

You can find the "FAI initrd" inside the nfsroot. /srv/fai/nfsroot/...../boot

That's not true nowadays.

That's part of live-initramfs, but you do not need to care about this.
FAI is runnung from /. AFAIK /live is only used during boot, before a
pivot_root is done.
