--- Comment #13 from Konstantin Svist <fry.kun at gmail.com> ---
FWIW, I've been dealing with fsck in emergency mode on a few of my machines
Note: Fedora 20, NOT using LVM; sda1 ext4 /boot, sda2 swap, sda3 ext4 /

>From graphical.target: 
systemctl isolate emergency.target switches to "emergency mode" but / is
mounted rw and can't trivially be remounted ro. Can't run fsck on rw,
obviously.

Editing grub to add "emergency" to kernel line, boots the / in ro mode, which
allows me to run fsck without any problem. As soon as I remount rw, however,
it's locked to rw.
