This uses [[settrans]] and [[storeio]] to create a ramdisk of 32 MiB by routing
a thusly sized [[zero store]] through the [[copy store]], connecting
that to the `ramdisk0` node, create a `ext2` filesystem on it, and replace the
translator running on the `ramdisk0` node with a instance of the [[`ext2fs`
translator|translator/ext2fs]] running on the same node ([[translator
stacking|translator/stacking]]).

A (better) alternative would be using the [[`tmpfs`
translator|translator/tmpfs]], but that one is broken at the moment.
