And as I said I know that you *can* run out of disk space and effectively break
your OpenWRT installation. As you can do with your mentioned
'dd if=/dev/zero of=/fill.bin' or with
'opkg upgrade `opkg list-upgradable | sed 's|\ .*||'`'
You can also break your router in plenty of other ways. But dd is still in.  I
also know people are dumb and will do it, but they are also creative and can
use google so they will do it anyway (and when I google for opkg upgrade,
workarounds to get opkg upgrade all back is the 3rd to 8th link showed on the
results page).

So from the replies so far I guess the only reason for disabling it is the try
to prevent people from doing stupid stuff, nothing really broken, right?
