Hi Dennis Lee,

Q: Did you build the added modules has kernal built-in objects, or as 
loadable objects ?

A: I was building the added modules as loadable objects.
Also I am working on systemctrl and initd systems.

Initially I included all the loadable modules(g_mass_storage, 
usb_f_mass_storage and g_multi) in
/etc/modules-load.d/modules.conf

Then after reboot it is showing the following message:

[FAILED] Failed to start Load Kernel Modules
see 'systemctl status systemd-modules-load.service'   for details.

systemctl status systemd-modules-load.service shows the following errors

debian@arm:~$ systemctl status systemd-modules-load.service

Q: Did you recreate the, uhm from memory, initramfs (or whatever the files 
loaded by u-boot are called) containing your added modules?

I didn't understand what is meant by uhm. Googling also didn't provide me 
the results.
Please explain it.

After I added the modules, the added modules were available in 
/proc/modules, which  indicates they are active.
But after reboot it is not availble in /proc/modules 

Also 

find /lib/modules/$(uname -r) -type f -name \*.ko  gives all the modules 
including 
g_mass_storage, usb_f_mass_storage and g_multi. I think this is the list of all 
modules built.

I am trying with systemctrl and initd systems. Please inform if I am missing 
something.
Thanks in advance for the help.


Thanks & Regards,
Sajeevan.K
