That's a great idea!
* Is it possible to use some different directory than /tmp/ ? My root
partition doesn't have enough space; could that be set in the
* Once the upgrade is complete, why throw away /tmp? If I use a
different directory, couldn't we have some bits in initramfs which
check for those and re-mount the aufs? Then after reboot, if
everything seems to work, could another tool copy back the aufs
contents to the real file system, to "commit" the upgrade? Or
doesn't that work for some reason?
