This sound very similar to what I am doing already with LVM and online
file system growing. A simple 'lvresize' and 'ext2resize' (or just
debian-edu-fsautoresize for those of us with that tool available)
later the full file systems have more free space again. :)

While I agree that tmpfs should be the default, I suspect this
argument isn't solid enough to make it worth it. There are luckily
other arguments too. :)
