Build in a snapshot

[luke-jr]

At least ZFS (and I suspect btrfs too) supports "forking" the filesystem and working on an independent CoW root. It would be nice if gentoo_update supported using this to build binary packages, while making sure there's no issues that will require human interaction (eg, new log messages printed, config files that need updating, etc).

If the latter occurs, it could then exclude those packages (and anything that depends on them) from the real install, and await instruction from the sysadmin.

Cool idea, but it might be a bit hard to implement.

I am also a bit concerned that not all filesystems support that, the most common ext4 (as far as I know) only supports something similar when lvm is used.

Anyways, putting it in the upcoming feature list, thanks! 🙂
