Title : Re: Multi user details questions.
Actually there is a minor issue for $HOME directory. On the *NIX
world, the actual user directory is /home/{username}. However, I
proposed /opt/usr/uid instead of /opt/usr/username. There is subtle
issue of assigning username in the literal form and I think using uid
instead of username is fine. The file standard hierarchy does not
specify the user directory name in detail and we just need to
maintain symbolic link of /home correctly.
I do not think that deriving from the reliable and well accepted
method of using the $HOME is the good idea.
Getting the $HOME from the environment is easy and reliable. It has
proven its value over the years.
+1 - also sticking to the freedesktop.org structure wherever possible
too. if we need to EXTEND it a bit and ADD some dirs - then let's
discuss that (where the fdo standards fall short) and then propose to
fdo these extensions.
For me, using uid in a file path which is in a non standard location
in the Tizen base platform should be avoided for two reasons :
1) it creates a new hardwired link between the login and the uid that
we might regret if we have to enforce Application isolation in a later
version of Tizen (4.0 ?) by the use of container.
2) it requires two rw mounting points on the any Tizen compliant
platforms. That add complexity to the Flash organisation (in
particular on device with only one small Flash) without adding any
extra value.
I would propose that for the base Tizen, we stick to the use of $HOME
in the compliance. Up to a platform manufacturer to create link (e.g.
with mount -bind) to other locations to provide backward compatibility
if needed.
