OK now I'm lost on the advantage of modifying the current bootloader
to do this, rather than boot from either Fedora 21 netinstall media,
or boot.fedoraproject.org media.

I've never seen this kind of notation before, and I don't see a
root=UUID= line so it seems like systemd is going to have no idea what
volume to mount as root fs.

What are vmlinuz-remote and initrd-remote.img? set root='hd0,msdos1'
is telling GRUB that those files are local, on the primary drive's
first partition. So where did they come from?

A particular Fedora installer version expects a particular environment
setup by a precreated initramfs which is on the netinstall.

I thought noselinux was deprecated a long time ago in favor of
selinux=0 or enforcing=0, with the latter being preferred since it
still labels files correctly.

The set root line in the grub.cfg tells GRUB where the kernel and
initramfs are located. That's it. Obviously it found
/boot/vmlinuz-remote and /boot/initrd-remote.img or the system
wouldn't have gotten to dracut. So it did exactly what you asked it to
do. I just don't know why you're booting the system this way instead
of using install media written to a USB stick or pxeboot or something.

It looks really short, I'm expecting a lot more data including journal
entries and there are none.
