[Users] deduplication

[suporte at logicworks.pt]

Absolutely agree with you, planning is the best thing to do, but normally people want a plug'n'play system with all included, because there is not much time to think and planning, and there are many companies that know how to take advantage of this people characteristics. 
Any way, I think another solution for dedup is FreeNAS using ZFS.

Everything depends on your needs, design planning. Maybe then sharing 
disk would be better to share via NFS/iscsi. Of course if you have many 
VMs each of them is different you will fail. But if you have mostly 
homogeneous environment you can think about this approach. Sure you have 
to have plan for upgrading "base" "static" shared OS data, you have to 
have plan how to install additional software (different destination 
than /usr or /usr/local)... If you already have your own build host 
which builds for you OS packages and you have already your own plan for 
deployment, you have done first steps. If you depend on upgrading each 
machine separately from Internet, then first you should plan your 
environment, configuration management etc. 

Well, in many times people do not do any planning, they just think some 
good technology would save their "poor" design.
