Indeed. But something is weird: I could successfully bootstrap GLASS, using
the installGLASS you provided me...doesn't this script use any github

Thanks. I indeed found other files in /tmp which were owned by a different
system user... I have removed them like "sudo rm github*" and "sudo rm

Still...same problem. I then tried stopping and starting stone again.
Still, same problem. Finally I drop the extent and I bootstrapped
everything from scratch again...why? because I thought some class var or
something could have been persisted with wrong stuff or garbage. So I
started again with that just bootstrapped glass and an empty /tmp and that

So I should wait for your fix to have multiple system users sharing the
same /tmp, right?

Let me know if I can be of help.
