well, there is a file node but it is completely empty ...

when using full disk encryption an fstab entry for the rootfs is
created dynamically in it from the kernel commandline args.

the actual read_fstab_entry() function in the initrd uses:

"for file in ${rootmnt}/etc/fstab; do" 

where $rootmnt is the already mounted rootfs disk (unless overridden
mounted in /root by default at that point)
