If you are looking at maintaining a collection of servers (which you 
presumably want to be practically identical, with the exception of a few 
files), why not have a sandbox master, which is in need of an upgrade, 
and then check the entire /usr /var /etc /and_so_on trees into a 
subversion server. Do the upgrade, figure out the issues, then check the 
upgraded version in. On the remote end, you could then log everybody 
out, and do a checkout. There would be a few issues with config files 
that need names, but it wouldn't be too bad.

I guess you'd want to look out for things like ssh keys and the like, too.

Anyway, it's an idea for keeping a collection of servers together.
