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

Bug introduced with this commit:

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

Comment 3 Steve Tyler 2013-08-11 11:47:58 UTC
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'

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.

There is already a "syncheck" target in the upstream Makefile, which does exactly that.

Added "syncheck" as a requirement to the "archive" and "rpm" target now.

Thanks and sorry for the inconvenience!

Comment 9 Steve Tyler 2013-08-14 11:37:22 UTC
Thanks, Harald. Doing the syncheck in the Makefile is even better ...

I don't see a recent commit message here:

Thanks:

Makefile: do syncheck before creating the archive or rpm
