Recently, I learned that you can now boot Fedora through grub2 without
an inetrd line. In fact, it will boot quicker. If you do, however,
grub2-probe, called from grub2-mkconfig will fail with the message
"cannot stat /dev/root" and any new kernel you've installed won't get
added to /boot/grub2/grub.cfg. As it happens, the kernel I'm using
right now has no such line and no initramfs in /boot, although two more
recent kernels did get an initramfs built.
I know that all I need to do is use dracut to create the proper
initramfs, then edit grub.cfg, adding the initrd line to the appropriate
place, but I'm having a bit of trouble locating the proper command line
for dracut. I find this frustrating, because I've seen it before, and
now that I need it, I can't locate it. I'd appreciate if it somebody
who knows would post the command line, so that I can correct this for
the kernel I'm using, reboot and then update grub.cfg properly.

The command lines I'd seen before were something more complex, using
uname -r to put the right version into place, but a little copy/paste
works too. I don't know why it is, but I can never find things like
that when I need them, even if I can when I don't.

i am same way. so i use 'tag' in firefox bookmarks.
then, when i want to find what i recall reading about, i use bookmarks
'search' to save 'strain on the brain'. this way, i only have to recall
what tag i used. ;-)
did you note at begining;
New Kernel Command Line Parameters
read the dracut.kernel.7 man page.
if i am following what you are wanting, the last link is what you want.
tho all in between and after are a very good read. long, but informative.
hthm.

As it turns out, the simplest example worked well enough for me to boot
into a current kernel with an initrd line, run grub2-mkconfig and get
the newest two kernels added properly. (They had everything needed,
they just needed to be added to grub.cfg.) There's still a few odd
things going on, but I'm at least one step closer to having my desktop
properly working again.

Quick dracut/grub2 question
joe zeff,
i just now pick up 2 more 'grub2' links you might be interested in.
they where just now posted to thread;
Grub2 upgrade issue
by;
Michael D. Setzer
replied by;
T.C. Hollingsworth
You'll need to rewrite them for GRUB2. Arch Linux has an good
overview of writing custom GRUB2 entries:
https://wiki.archlinux.org/index.php/GRUB2#Configuration
And, the complete syntax for GRUB2 menu entries is listed in their
manual:
http://www.gnu.org/software/grub/manual/grub.html
do not know it they will help you anymore, but they look interesting.
