The real difference is what level of security you require. There is a difference between needing to protect against other users' processes and needing to protect files. Sort of like the difference between locking your door to keep intruders out vs carrying a gun around your house. :-) Both can be equally effective at proteccting your stuff. Locking your door is a single point of entry and therefore a lot easier. :-) >will it be possible, with way 1st, to run some program as root, >like you do in Linux when you download an rpm as user and install >it as root, after providing the root pwd? I'm just asking... Not at this time. I *certainly* see the value in that. I *hate* having to reboot/log out to install. But since multi-user is > R1, who knows? :-)
