There needs to be a "then" on line 65:

$ less -N dracut-initqueue-1
...
     65     if [ $main_loop -gt $RDRETRY ];
     66         if ! [ -d /sysroot/etc/fstab ] || ! [ -e /sysroot/sbin/init ] ; then
     67             action_on_fail "Could not boot." && break
     68         fi
     69         warn "Not all disks have been found."
     70         warn "You might want to regenerate your initramfs."
     71         break
     72     fi
     73 done

systemd/dracut-initqueue.sh: continue to boot if finished failed

After an update, installed rawhide systems may hang during booting with the message in the bug summary displayed.

The easy workaround is to boot an earlier kernel.

The hard workaround is to boot into rescue mode from an F19 installer disc[1], fix dracut-initqueue.sh[2], and rebuild the initramfs with:
# dracut -f --kver <latest kernel version>

[1] You could probably do this after booting an earlier kernel, but I did not test that method.

[2] Per Comment 1. The full path is:
/usr/lib/dracut/modules.d/98systemd/dracut-initqueue.sh

Tested with:
$ qemu-kvm -m 4096 -hda f20-test-1.img -cdrom ~/xfr/fedora/F19/Fedora-19-x86_64-DVD.iso -vga std -boot menu=on

Eventually, a dracut shell prompt is displayed with a message suggesting that you buy a USB stick as a dracut debugging aid ... :-)

Here are some timestamps from boot.iso:

$ isoinfo -lR -i boot.iso | egrep 'squash|vmlinuz'
-rwxr-xr-x   2    0    0         5652376 Aug  7 2013 [  31354 00]  vmlinuz

In the future, it might be a good idea to do a bash syntax check using
the bash "-n" option
before committing any changes.

Doing that would have caught this problem immediately:

$ bash -n dracut-initqueue-1 
dracut-initqueue-1: line 72: syntax error near unexpected token `fi'
dracut-initqueue-1: line 72: `    fi'

$ bash -c 'help set' | less -N
...
     16       -n  Read commands but do not execute them.

I tested this method and it works.
