RE: [Xen-users] Making system templates

[Nathan Eisenberg <nathan@xxxxxxxxxxxxxxxx>]

Certainly it's hard to claim that any one way is always 'best'.  Ultimately, 
being closer to current is generally better than being further away from it - 
not that this is exactly news to anyone.

My solution is very close to Thomas', except that I debootstrap from a local 
mirror which is updated only after the upstream packages are tested against 
common configurations.

That way, I can use debootstrap to get my definition of 'current-stable', while 
simultaneously being reassured that the packages I am pulling down are of a 
version I have tested and verified to work.  This is part of my upgrade cycle, 
so if I add a tenth machine to a cluster using the debootstrap method, I am 
pulling down the same version of packages as those already on the production 
machines

Too fast or too slow ... Unexpected changes introduced into an
environment can cause grief. I'm only challenging the assertion that
"The best way" is to create each new machine on the fly. Whether or not
it is best depends on organizational needs.
