At the risk of sounding like an ignoramus:  In a *server* OS, what exactly
is gained by encryption?  Unless the plan is someone physically sitting at
the console to type in the decryption key (for every zone??) on every boot,
the machine needs to have the decryption key accessible at runtime to
function.  Which makes the whole enterprise a bit like buying a fabulously
secure lock for your house that you have to leave the key in at all times
or the house falls down - why bother?

I get that people *think* it buys them something, or may be required to do
it by someone who does.  But is that anything more than an illusion?  I
mean, yes, it could live on the USB key and if the server is off someone
can take the key away and the data on the disks is not decryptable if
someone walks off with the server.  But under what circumstances is that
useful?
