I think I am beginning to understand what went wrong, I installed
VirtualBox and all
my troubles started after this. Everything was smooth until I tried to
compile a kernel.
This is when things went sideways. So if your going to be compiling
kernels stay away
from VirtualBox on Debian.

So as much as I do not care for systemd because it deviates from the
original philosophy of do one
thing but do that one thing really really well and better than anyone
else policy to do everything under
the sun ( and so far seems to do everything under the sun really
well). It was 'me' who did this 'not'
systemd. I am human, humans err ?

Systemd is impressive and scares me at times but then I guess it comes
down to personal choice ?
I keep asking myself 'if' something bad happens to systemd, what are
our options ? Think about it ?
It is not like tweaking init using text files and echo eh ?

Uh-uh no it does not.

I guess  it is looking for that 'vmhgfs' because I installed VirtualBox.
And something really interesting, I deleted VirtualBox or so I
thought. I recompiled the kernel
and checked, same 'bleeping' error. So reinstall VirtualBox and like
some Voo Doo magic all
my operating systems showed up which tells me Virtual Box keeps its
folder and settings in
your home folder. One lives and learns :-)

oh-kay so here are the latest developments. I told initramfs to load
crc32c, told make menuconfig
to disable Virtualization then recompiled and re-test and my kernel
drops to a initramfs shell ( some progress yay )
then I ask initramfs to load 'vmhgfs' and it complains about 'can't
find module not in blah-blah' and reverts to the
original error, so I am back to square one.

sudo vim /etc/initramfs-tools/modules ( in Debian ) for anyone curious :-)

Valdis, if I apply that patch to 'my' kernel and it works then problem
solved right  ? What do you think ?
And you do have nice things my friend, remember a young lady some
years back wrote in her facebook...
"Drove a Jag, did not crash"  ? :-)

I am going to keep working on this as and when I have the time I want
to know how to fix this.
We know it is because I installed VirtualBox, now I gotta find a fix :-(

Thanks everybody - Aruna
