Hi,

i try to update my oVirt Nodes from 4.5.3 to 4.5.4 but it always fails on my 
hosts. Watching the rpm install process i see that the rpm is building the boot 
image/bank and /var/tmp filling up quickly. Looking deeper into this folders i 
see that there is a dracut folder created by the update process that contains a 
urandom file with the size of all available space in /var/tmp.

[root@ovnode01 dev]# df -h

For me it looks like that imgbase (or whatever build this images) copies 
/dev/urandom into the new image, as expected this is not possible. Anyone know 
an workaround for this issue?
