Indeed - and it was apparently me some years back that changed it

2nd try: make amd64, i386, sparc64 and vax iso images use full sets.
While there fix an old bug that makefs used the build hosts /etc/group
and passwd information when creating the image.
Thanks to Andreas Gustafsson for extensive testing.
I dimly remember trying to get memory usage down for VAX CDs, and the tmpfs
costs kernel memory. Back then I saw no downside with this aproach - but now
you have shown there is ;-)
I'll make it configurable and only have VAX use the expanded /dev, leaving
it empty for all others, so init will union mount the tmpfs automatically.
Let me fire up a test build....
