Many thanks

About “What about sdb root on?”, here is the help info about “sdb root on|off”:
……………………………………………..
sdb root <on|off>            - switch to root or developer account mode 'on' 
means to root mode, and vice versa
………………………………………………

I mean if we can still use “root” user by “sdb root on”? and can user “su” to 
normal user for app launch?

Best regards,
Yugang

Hi, IVI multiple users component


Recently, we found some unstable changes in multiple users support which 
blocked our test automation/tests deployment automation tools. So if we have 
detailed specifications about below items?

What are the issues/bugs? This is very important to better understand what are 
you looking with your questions below.

1.       What is the default user of “sdb”? how about the “sdb” support on 
Tizen common? How about “sdb root on” on Tizen? Can SSH use normal user to 
login the Tizen?
A lot of questions here. ssh login works, sdb root off uses 'developer' 
(however, 'developer' cannot start apps in IVI). What about sdb root on?


2.       Where is the common media path(just like the “/home/app/content/…”) 
for a special normal use on Tizen? Is there a sharing folder for media files 
for all normal users?

3.       What is the difference between guest and normal users and system 
initial users(bob, Eric….)? and how about the schedule of removing “app” user 
and related folders/ in IVI mechanism?

In IVI image today, guest is not used for anything. Only 'app' starts its own 
weston and is able to run apps (unlike in Common where all demo users can have 
applications due to a shared weston instance). IVI has no plans removing 'app'. 
We are working on 'multi-seat' enablers but that does not mean 'app' needs to 
go away.

4.       The details of “Tizen 3.0 security mechanism” and multi users:

a.       Normal users can only launch/list the app which be installed by 
themselves?

b.      If the privilege will impact normal user’s security mechanism? E.g. 
system folder permissions, guest users permission….
