Description of problem:

I have been running F17, triggered the upgrade via fedup and when I came back to the computer it was unbootable.

Version-Release number of selected component (if applicable):

fedup.noarch                         0.7.1-1.fc18                installed      

How reproducible:

I have not tried reproducing the bug.
  
Actual results:

On the screen there were some messages saying that mounting my (encrypted) harddisk failed. Sadly I don't have the specific message written down (my theory here is that the system rebooted during upgrade, waited for my harddisk passphrase and hit some timeout -- hence, the system did not came up).

Expected results:

I would have expected the system either to wait forever until I enter the passphrase or when it hits a timeout at least offer a convenient way to continue a this stage.

So, I rebooted the system and it didn't come up -- it simply displayed the fedora logo for about 30 (?) minutes doing nothing (no harddisk activity). I had to disable the graphical boot and then I saw an error message (can look up the specific text on my camera if that is necessary) mentioning D-BUS and systemd, trying to connect to some socket which fails with a connection refused error.

Additional info:

I did some trial-end-error debugging and figured out that removing the following parameter systemd.unit=system-upgrade.target from the kernel boot line makes the system comes up just fine. Currently, without any manual changes, the entry in /boot/grub2/grub.cfg looks like this:

linux   /vmlinuz-3.6.7-5.fc18.x86_64 root=/dev/mapper/vg_lily-lv_root ro rd.md=0 rd.dm=0 rd.luks.uuid=luks-e7d3371d-e50a-4c5a-a1af-380b7009c045 rd.lvm.lv=vg_lily/lv_root  KEYTABLE=us SYSFONT=latarcyrheb-sun16 rd.lvm.lv=vg_lily/lv_swap LANG=en_US.UTF-8 rhgb quiet systemd.unit=system-upgrade.target

I was told on IRC that the last parameter is not supposed to be there. So it seems it is some kind of leftover from the fedup upgrading process. Maybe it is related to the upgrad process finishing unexpectedly duo the encrypted harddisk.

Thank you very much,
