Where you using "rsync -a -e ssh 172.16.15.2:/ /a/root" ?
It is not clear what have you done. What I did was to put hd into
diskless client machine, installing Fedora OS on it, updating,
configuring and tweaking it, starting sshd and then copying it to server
with rsync. At least, it was what docs said to do.

etherboot will load initrd from nbi image into /dev/ram0.

correct.

After you create snapshot with redhat-configure-netboot you will find a
files /tftpboot/linux-install/pxelinux.cfg/ with name in hex numbers
(client ip address). This is your cheatlist for parameters to create for
nbi image.
In your case it would be more like,
/usr/bin/mknbi-linux --append "noauto root=/dev/ram0 init=disklessrc
NFSROOT=172.16.15.1:/a ramdisk_size=10000 ETHERNET=eth0" vmlinuz
initrd.img > vmlinuz.nbi
You should understand that the initial root dir is ram drive, not nfs,
and "init=disklessrc" is important because it will mount nfs and
snapshot directories. Check your NFSROOT again.
Also there was some confusion with mknbi-linux binary. I found another
version of mknbi-linux in /usr/local/bin that generated images I was
unable to boot. Then I installed redhat original mknbi with "yum install
mknbi" which installed mknbi-linux in /usr/bin, that's why I write full
pathname. I don't know what's the differences. All I know that rpm
version works and the other does not.
I hope it helps.
