Another view: I've had a USB hard drive set up to do this for some
years, but the strain of living in my jacket pocket may be telling,
it's getting a bit unreliable. But it boots on everything I've ever
tried except one machine (OK, two, but I wouldn't bother trying i386
software on an ARM-based Raspberry Pi). There's one suggestion: if you
install i386/486/whatever it should also run on 32-bit hardware. I have
a 32-bit netbook, and you may one day want to deal with an older
machine. It's quite useful to have a pocket-sized PC containing all the
software you want, just needing the addition of pretty well any loaned
PC wherever you happen to be. It beats carrying a laptop... it also
means that if I do have my Windows 8 laptop I can [fairly] safely use it
on public wifi.
On the desk in front of me at this very moment is a USB stick with an
i386 sid installation. It's still text-based, I haven't yet added any
graphical software, I'm waiting for the combination of time and
enthusiasm to troubleshoot an odd networking problem. It boots up fine
on my netbook and laptop, but on my main desktop, it has no Ethernet
connection after booting...
Why you may be barking up the wrong tree is that all the software is
there, but the Ethernet interface is not being brought up. DHCP on my
network is not being used, though the DHCP client is installed. If I
bring up the interface manually with a suitable IP address, all is
well. Try that exercise in your situation, my assumption would be that
if you can bring it up manually then you have the right drivers
installed. By manually I mean using ifconfig or other networking
software, without the need to bring in any extra modules with modprobe.
So no, I don't have the answer yet, but it may be the same problem. The
USB hard drive was installed using the same desktop machine, the USB
stick was installed with my laptop, both i386 installations made while
running on amd64 hardware. I don't know yet if this is significant, but
certainly if I had installed to the USB stick while plugged into the
desktop, I would expect networking to behave properly on that machine.
Of course, it might not then work on the laptop...
I haven't got around to finishing the job as I'm considering buying a
small SSD for this job, which would give me more speed and space than a
USB stick while being mechanically more reliable than my current pocket
hard drive.
