Comment # 52 on bug 935993 from Walther Pelser

So I did: (See latest attachment)
But: It didn't boot!

You are on the right way, I think. I noticed earlier, that dracut had changed
all my older SUSE-kernels. In the beginning they were booting fine. Then I
installed my own kernel and I could boot all my installed kernels. But one day
there came a new dracut version or something else, I noticed that all initrds
from all installed kernels were rewritten. From that time I could only boot
with my own kernel. No older SUSE-kernel even after deleting and
re-installation did work anymore. And no new SUSE-kernel did work too. And I
also tried to rewrite dracut with force by choosing the SUSE-kernel. This did
not change anything.

So I could offer to delete all kernels from /boot and then install only the one
mentioned above. It should work because dracut can no longer look into other
kernels.
