The rest of the devices will be created by udev when it > runs at boot time. null and console are the absolute irreducible minimum but there's one that can be dispensed with if the correct kernel option is enabled. We don't need everything that makedev traditionally provided (like every block device type known to man, floppys and ancient ptys) but the rest number about ~250 and are useful in single-user mode if udev fails to start. Considering that ~250 devices consumes a teeny-weeny bit of disk space and they are hidden from view normally, I say it's worth it leaving them in. Which is what vapier also says. -- alan dot mckinnon at gmail dot com
