Do you have the "before" and "after" versions of the config files you
changed (I'm guessing /etc/network/interfaces, and maybe also
/etc/udev/rules.d/70-persistent-
net.rules ?

Doesn't Ubuntu in general do that?  In fact, don't most Linuxes in
general do that?

I've always had to edit /etc/udev/rules.d/70-persistent- net.rules or
its equivalent when migrating Linux server images to new hardware, or
replacing NICs in servers... I don't generally move desktop machine
images around, but I had expected they would need the same tweaking.

Are you sure that an Lubuntu desktop install can be migrated to new
hardware with different NICs and *not* need any manual fixup of
network configuration files?  Maybe I am just too stuck in the world
of servers!?

I can probably test this in a VM, by editing the MAC address of the
virtual NIC in the VM.  I might try that tonight when I get home.

No.  That depends totally on the video hardware of the "real machine".
If it uses a real video card, there is generally no subtraction.  If it
uses shared RAM for video, then that takes away some few MB from the
RAM available to Linux.  You can usually configure how much it takes
away in the BIOS.

Sure.

I think at minimum we would have a note saying that installing Lubuntu
in less than 256MB is not recommended, but for those with a spirit of
adventure, see <some wiki page> for ideas that might help them.  What's
the point of testing the netboot mini.iso if we then do not document its
existence?
