It's rootfs binaries that are shared, not configuration. It's
unfortunate but works OK for the single user use case it's meant for.
It's obviously not a proper solution for the generic case. We were
hoping that we could use something like overlayfs to hide the issue
under the rug. Do you think that's also a really dumb thing to do?
Using block device snapshotting would be interesting and we should
definitely look into that.
