I wanted to comment on blog post this morning. It is hosted on blogs.gnome.org, which requires me to login or create an account. I tried to create an account but it refused because my email is invalid. Google helped me to find that to request a blog we need a gtk.org, gimp.org or gnome.org email alias so I guess this is the same.
What is the point of having a blog where only a few people can comment on ?
Regarding the blog post itself, I wonder how it was installed. It looks like this is the proprietary version as it as usb support. Virtualbox now works fine without usbfs support so I guess some service is wrongly mounting it. And at the wrong place.
Update: as Pavel wrote in a comment, this would be a choice of the author of this specific blog, not the platform. I still think this choice is very wrong.
