[indiana-discuss] Adopt Indiana personalities (GNU and SUN)

[Josh Lange]

I see the advantage as being able to SVR4 scripts seemlessly (have
SUN_PERSONALITY set automatically by the package manager), as well as
letting users opt to have all their scripts/commands to work just as they
would on another sun box (ex. in the case of networked home directories,
legacy, etc).
