If I'm reading you right you commented out the only setting that tells
the machine how to set up eth0, and now you're wondering why it doesn't
know how to set up eth0? The ifup/down scripts use the settings from
/etc/network/interfaces, so if they're gone the scripts won't work. You
could try uncommenting all the eth0 settings except the 'auto' one. I'm
not sure but I /think/ that will stop it coming up at boot, but still
allow ifupdown to work. Note though, that if the line is 'auto eth0 lo'
you'll need to make sure there's still an 'auto lo' entry somewhere
otherwise bad things may happen.
