Okay update time. Irrespective of where I install VirtualBox from if
a new kernel
is installed then I have to manually create a new initramfs
otherwise systemd-modules-load.service fails at the boot.
When it comes to VirtualBox from Oracle I find that statement "odd" to say the
least.
When I install the VirtualBox from Oracle it installs
/lib/systemd/system/vboxdrv.service. When the system starts if there is no driver
matching the running kernel it will be built and then loaded.
This results in....
[egreshko@meimei ~]$ systemd-analyze blame
52.215s vboxdrv.service
And in the journal....
