    I should have thought to try that ... glad you did :-)

   Its really unfortunate it doesn't work tho ... this is such a great
feature .. anyway around this ? Any chance of tagging up with google
chrome developers to find a solution ?

   I don't understand because I am ignorant in large part on selinux
details - does chrome want to transition to a new selinux type ? Can we
make that namespace 'equivalent' to sandbox_web_t or some way to make
the transition allowed without really leaving your sandbox? Sorry if its
a dumb question ..



   Good that firefox works, but chrome is growing really fast ... be
good to find a way to make this fly ...
