Fedora doesn't ship lsb_release anymore. So try to read /etc/os-release
to find whether distribution is Fedora.
If Fedora is found, generate a new initramfs suffixed with -compat-drivers
to not override the distribution kernel's default one. Also add a new
kernel entry to grub2 configuration without overriding the default boot
entry.
