Omnia 4849 - require-root for install

[richardhenwood-dell]

I'm very excited about the work in #4849

An initial observation that I've been pondering. Omnia during install requires write access to /etc/omnia (and another location in etc). etc is typically writable only by root. Today to install Omnia you need root access.

I'm opening this issue to discuss if this is a sensible design constraint.

I feel like require-root for install may be desirable:

• Omnia is a provisioning tool that may have a large scope of influence. It does root like things to the system.
• We want to use standard OS features for audit, logging, etc. Having a 'root-required' step makes this easy to setup during install.

Also, I feel like require-root may not be desirable:

• writing to /etc is an artificial requirement - we could change /etc/omnia to a user configurable location.

On balance, I think my instinct is that we should require-root (the current behavior) for install. Anyone have alternative thoughts?

Omnia also adjusts firewall rules to allow NTP and NFS. Adjusting firewall rules requires root.
