Graphics does not start unless I chmod a=rwx /run/user/0

Question

Hello, I boot Arch Linux 2014.04.01 x86_64 Live CD, do
pacman -S xorg-server xorg-xinit i3 xf86-input-synaptics xf86-video-modesetting
useradd someuser ; mkdir -p /home/someuser ; chown someuser:someuser /home/someuser
su someuser ; cd /home/someuser
and put i3 in .xinitrc as per the wiki.
I run startx as someuser, but the graphic environment will not start, and in Xorg's log I read it cannot write in /run/user/0, check permission. Then I do ''chmod a=rwx /run/user/0'', and startx works.
This additional step is not mentioned in the wiki. Am I doing something wrong or missing something? Thanks,

Where did you get this idea?  This is the problem.
Follow the wiki
Also, you realize everything you are installing and doing only remains in memory.  Why are you installing all these packages?  Are you going to repeat this installation and user creation at every reboot?
EDIT: something else is wrong too - but until you fix the above, it will be hard to know if it is a separate cause, or an indirect effect.  /run/user/0 should not be relevant, but /run/user/1000 should be used.  I suspect your method of starting X is logging out of the 'su'ed user and is dropping back to the root login that it is under.  You'll likely need to change tty's to log in as your user - on a normal system you could log out of the root session and back in as your user - but on the iso I think autologin for root is set on tty1.  Of course you could disable this too.
