[orca-list] updating to fedora rawhide

[Pavel Vlček <kontakt pavelvlcek eu>]

Hi,
I want to try fedora rawhide. I found this manual or this command, how 
to do this.
fedup --network rawhide --nogpgcheck --instrepo 
http://download.fedoraproject.org/pub/fedora/linux/development/rawhide/$(uname 
-i)/os/
but when I enter this command, I get an error about 404 not found boot 
images. When I enter it without instrepo, packages are downloaded, but 
after reboot, I get error about kernel problem. When I use yum, packages 
are downloaded, but when fedora wants to update rtkit, yum stop working 
and my system is broken.
Can someone help with this? I want to get all up to date, I have the 
same problems, when I want to update to fedora 22 with yum and with fedup.
Thank you,
Pavel V
