Description Ondrej 2015-08-11 08:49:52 EDT
Description of problem:
When upgrading a kernel on a machine witch not sufficient space in /boot, dracut produces an invalid initramfs. No warning/error message is displayed.
Machine can not boot after that

How reproducible:

Steps to Reproduce:
1. make sure there is little space in /boot (say 10Mb)
2. run "yum update kernel"

Actual results:
initramfs for the new kernel is produced, but it is incomplete.
No warning/error message is displayed

Expected results:
dracut should complain loudly if there is insufficient space in /boot
