Wow. A *minimum* of 10Gb for /var and /var/log? Surely only fairly large
servers need that sort of room...

(and why is /tmp given space on the physical disk at all? tmpfs it!)

Personally I've found 200Mb to be way more than enough for /; I could
probably survive with a 50Mb / but it would be tight. With / being
loaded off LVM(-on-RAID) and with online resizing in the upstream kernel
it's not as hard as it used to be to resize / without any downtime.

This latter point has saved my bacon repeatedly.

How do you boot without /lib? ;)

It's appropriate on very small systems: one box I use regularly has less
than 80Mb available. Cutting that up seems pointless.
