Hello,
I am experimenting with systemd on redhat 6.
I have built 2 custom kernels:
1. one is essentially a desktop kernel (essentially a fedora kernel)
2. one is a stripped down kernel with many things removed.
on a normal redhat 6 box both of these kernels work without issue.
on my test systemd boxes only the desktop version is working, it fails
with the following, and drops to a shell:
Please see below for relevant outputs.
My question is what kernel options are explicitly needed for systemd
if needed i can supply my kernel configs as well.
version systemd-36
