*** This bug has been marked as a duplicate of bug 730357 ***

Correction:
The symptoms looks exactly like bug 730357, but it seems like it is caused by booting without initrd:

[root@dev-mk ~]# cat /proc/cmdline 
BOOT_IMAGE=/boot/vmlinuz-3.4.6-2.fc17.i686.PAE root=/dev/sda3 ro quiet rhgb

[root@dev-mk ~]# grubby --grub2 -c /boot/grub2/grub.cfg --add-kernel=/boot/vmlinuz-3.4.6-2.fc17.i686.PAE --copy-default --make-default --title 'Fedora (3.4.6-2.fc17.i686.PAE)' '--args=root=/dev/sda3' '--remove-kernel=TITLE=Fedora (3.4.6-2.fc17.i686.PAE)'
grubby fatal error: unable to find a suitable template

Debugging shows that it is caused by:

[root@dev-mk ~]# grep ' / ' /proc/mounts
rootfs / rootfs rw 0 0
/dev/root / ext3 rw,seclabel,relatime,data=ordered 0 0

[root@dev-mk ~]# ls -l /dev/root
ls: cannot access /dev/root: No such file or directory


It looks like a kernel bug to me that it reports /dev/root in mtab when it doesn't exist in /dev.

Reassigning to kernel.

I am using the following workaround till this is fixed:

cat > /etc/kernel/postinst.d/rhbz833011  <<_EOF_
#!/bin/bash

# We're passed the version of the kernel being installed
inst_kern=\$1

GRUBCFG=/boot/grub2/grub.cfg
cp \${GRUBCFG} \${GRUBCFG}.pre_\${inst_kern}

# initramfs is unneccessary for a laptop with only one disk
sed -i "s/.*\/boot\/vmlinuz-\${inst_kern}.*/\\tlinux \/boot\/vmlinuz-\${inst_kern} root=\/dev\/sda1 rootfstype=ext4 ro rd.luks=0 rd.md=0 rd.lvm=0 rd.dm=0 KEYTABLE=us SYSFONT=latarcyrheb-sun16 LANG=en_US.UTF-8 selinux=0 intel_iommu=on i915.semaphores=1 i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1 slub_debug=- plymouth.enable=0 raid=noautodetect libahci.ignore_sss=1 quiet/g" \${GRUBCFG}
sed -i "s/.*initrd \/boot\/initramfs-\${inst_kern}.img/\\t#initrd \/boot\/initramfs-\${inst_kern}.img/g" \${GRUBCFG}
_EOF_

I am commenting the initramfs line instead of deleting it so I can return easily when needed.

To finish it of it needs this:

cat > /etc/rc.d/rc.local <<_EOF_
#!/bin/sh

# grubby needs this one
ln -s /dev/sda1 /dev/root
_EOF_

Be careful, this one overwrites any rc.local file, you may just want to add the 'ln -s /dev/sda1 /dev/root' to your own rc.local file.

And off course make sure the rc-local.service is started:

systemctl enable rc-local.service

This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '17'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 17's end of life.

Bug Reporter:  Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 17 is end of life. If you 
would still like  to see this bug fixed and are able to reproduce it 
against a later version  of Fedora, you are encouraged  change the 
'version' to a later Fedora version prior to Fedora 17's end of life.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
