I just found myself having to set up a new CentOS 6 system with a nearly identical configuration to an existing host, so I thought I would just

1. Do a minimal install to set up partitions etc. on the new system.
2. Create an image of the existing system using Clonezilla
3. Run a Clonezilla restore on the new system.

- as I though it would be a lot simpler than replicating the exact package selection, installing the same users, doing the same manual config edits (which are required) etc.

It turns out that it wasn't quite as easy, though. The problem is that the system use LVM2 volumes for the filesystems, and the new host has a slightly smaller disk than the other, and Clonezilla seems unable to restore to a volume that's smaller than the one that was cloned - even if the actual data fits.

I guess I could temporarily reduce the LVM volume sizes on the existing units and clone again, but I'd rather not if I can avoid it. Just copying file-by-file could be an option, too, but I somehow feel less comfortable doing that than the above; there is something about the way I could end up with a mixture of my "minimal install" and the "cloned" data, I suppose.

Does anyone have any other ideas about how I might achieve what I want?
