If you have a grid with multiple machines, each with a dedicated system role,
should each system role get his own user?
Like one user for file servers, one for auth, one for venti, and one for cpu servers.
Is there any point in doing that or is it better to only use one user (bootes)
on all these machines?

I'm not sure what the prevailing wisdom on this is at this time, but for
whatever it may be worth[less], my own small cluster I have set up with
a separate host owner per system role (one for the file server, one for
the auth server, and one used by both of my CPU servers). I'm not
currently using venti.

Yes, if you share one authserver, then you'd have to use different
users in order to be allowed to use different passwords. If you're
fine with somebody finding out one password being able to access all
your services, then it doesn't matter.

My was has always been to have a file system user and an auth server
user that are used ONLY for those roles.
As for CPU servers, it really depends on how you use them. The
main reason you might want to have different CPU server owners is
to control access to physical hardware. E.g. I have machines that
are used to control my radios via their serial and USB interfaces.
For those, I don't want the "general pupulation" to have access to
that hardware, so I run those servers under a userid that is distinct
from the "general purpose" CPU server owner.
Oh, the Pi I use for bluetooth dev work has its own host owner,
for similar reasons.
I'm sure there are other cases, but that's the only one where I've
personally had a need for multiple host owners.

agreed. compartmentalization might be used to have less
users/passwords than servers. if two cpu servers are used
interchangably for the same usecase by the same end-users, why not
give them the same credentials.
next time please try to quote correctly, lyndon.
