Description of problem:
somesthing seems to be broken in dracut-008.7: the root file system cannot be found!

starting with the update to dracut-008.5 I need to start with "selinux=0" (or in permissive mode to get a getty from systemd, otherwise systemd seems to fail to start the gettys!

Comment 1 Thomas Meyer 2011-02-23 19:18:34 UTC

okay, after some debugging I found the problem:

dracut seems to be very strict about non-existing resume devices. I need to remove this option from my kernel command line: "resume=/dev/mapper/luks-swap".
with the above option removed, the system boots correctly. with above option in place dracut tells me that it cannot find the root file system, which is not true.

/dev/mapper/luks-swap is an LUKS encrypted swap device, that was not setup/mounted/existing while the dracut tool created the initramfs (because of some bug in plymouth/systemd that don't let my enter the password in the boot process...)

oh.. that might be a very valid point. 
1. dracut has to be more verbose about what failed
2. dracut should not completely fail after it did not find the resume device
