installing Debian on USB flash drive for use in many machines
debian-user:
I am continuing to work on the idea of installing Debian on a USB flash
drive for use in many machines, primarily for diagnostics, maintenance,
repair, backup, archive, imaging, etc..
Yes, I am aware of Debian Live, etc., but I'm going down this path as
much as a learning exercise as for "Git 'r done!".
I am using two computers for my experiments:
1. i72600s -- homebrew, Intel DQ67SW motherboard, Intel Q67 Express
chipset, Intel Core i7-2600S processor.
2. i72720qm -- Dell Latitude E6520 laptop, Intel QM67 Express chipset,
Intel Core i7-2720QM processor.
As you can see, the machines are somewhat similar.
I have installed Debian 8 amd64 onto an SSD in i72600s with the
following tasks:
Debian desktop environment
Xfce
Print server
SSH server
standard system utilities
I have also installed cifs-utils, virtualbox, and some other software.
I have installed Debian 8 amd64 onto a USB flash drive in i72600s with
the following tasks:
SSH server
standard system utilities
Very little additional software has been added.
The SSD seems to work correctly in both machines.
The USB flash drive seems to work correctly in i72600s.
But, Ethernet does not work when I put the USB flash drive in i72720qm.
I'm trying to figure out why Ethernet does not work in i72720qm when
using the USB flash drive.
My theory is that I'm missing software (device driver?) on the USB flash
drive that is required to make Ethernet work on i72720qm.
So, I have run 'lsmod' on i72720qm in each of the two configurations.
Here is a comparison ('<' indicates module only present when running USB
flash drive, '>' indicates module only present when running SSD, no
marker indicates module present in both cases):

Of the 21 additional modules (arc4 ... vboxpci) that are present when
running the SSD, I don't recognize which one(s) might be what I need to
get Ethernet working on i72720qm.
(Then again, I don't even know if I'm barking up the right tree.)
I have attempted to RTFM and STFW, but have found both too much and too
little information; much of it obsolete.
Any ideas?
David
